interchangeable. They solve different problems. One freezes a load sitting on trays, the other freezes piece by piece. Getting this wrong at the design stage means the wrong machine, the wrong room size, and the wrong insulation spec.\u003C/p>\n\n\u003Cp>This article compares the two on technical numbers, product fit, and what each one demands from the building itself. We write as a panel manufacturer, so the parts equipment vendors rarely cover, namely walls, floors, and airtightness, are included here.\u003C/p>\n\n\u003Ch2>What Actually Separates IQF From a Blast Freezer\u003C/h2>\n\n\u003Cp>A blast freezer, or air blast freezer (ABF), is a room or cabinet where product sits on trays and racks while high-velocity air at roughly -35°C to -40°C removes heat. The process is batch based: load, freeze, unload, repeat.\u003C/p>\n\n\u003Cp>IQF, short for Individual Quick Freezing, is a continuous process. Product travels on a belt through a tunnel held below -35°C, and each piece freezes separately instead of clumping into a block. The output pours freely, so it can be reweighed and packed per portion.\u003C/p>\n\n\u003Cp>Both answer to the same quality benchmark. Codex Alimentarius CXC 8-1976, adopted in 1976 and last revised in 2008, requires quick frozen foods to reach and hold -18°C or colder at the thermal centre, at every point in the cold chain. Indonesian SNI practice for frozen fish uses the same -18°C core temperature.\u003C/p>\n\n\u003Cp>One distinction gets lost on site: -18°C is a storage target, not a freezing target. Blast freezers and IQF tunnels get product there; cold storage only holds it. We covered that split in more detail in our \u003Ca href=\"https://sandwichpanels.id/en/blog/blast-freezer-vs-cold-storage-2026\">blast freezer vs cold storage comparison\u003C/a>.\u003C/p>\n\n\u003Ch2>Technical Comparison: Speed, Ice Crystals, and Drip Loss\u003C/h2>\n\n\u003Cp>Freezing duration is the number that drives product quality, because it decides how large the ice crystals grow inside the tissue.\u003C/p>\n\n\u003Cul>\n\u003Cli>\u003Cstrong>Freezing time.\u003C/strong> IQF freezes each piece in minutes, typically 3 to 15 depending on size. A blast freezer works per load: thin fillets take 30 to 90 minutes, shrimp blocks around 2 hours, and thick cuts or full loads can run several hours. Reference figures for fish are published in the \u003Ca href=\"https://www.fao.org/4/v3630e/v3630e06.htm\" rel=\"nofollow\">FAO document on freezing time in fisheries\u003C/a>.\u003C/li>\n\u003Cli>\u003Cstrong>Ice crystal size.\u003C/strong> Slow freezing produces crystals above 100 micrometres that rupture cell walls. IQF systems produce crystals below 25 micrometres, so cell structure stays largely intact.\u003C/li>\n\u003Cli>\u003Cstrong>Drip loss on thawing.\u003C/strong> IQF product typically loses 3 to 8 percent of its weight, against 10 to 20 percent for block frozen equivalents. That gap works out to a 30 to 50 percent reduction in loss.\u003C/li>\n\u003Cli>\u003Cstrong>Output format.\u003C/strong> IQF yields loose pieces ready for portion packing. A blast freezer yields blocks or trays that must be broken up before repacking.\u003C/li>\n\u003C/ul>\n\n\u003Cp>For shrimp and cut fruit exporters, the drip loss gap shows up directly in the accounts. At 1,000 kg of throughput per day, a 7 percent difference means 70 kg of product per day leaving as water on the customer's counter.\u003C/p>\n\n\u003Ch2>IQF Machine Types and Their Capacities\u003C/h2>\n\n\u003Cp>IQF is not a single machine. Three configurations dominate food industry practice, and each one demands a different room shape.\u003C/p>\n\n\u003Col>\n\u003Cli>\u003Cstrong>Fluidised bed.\u003C/strong> High-velocity air lifts small pieces so they freeze while suspended. It suits peas, sweetcorn kernels, berries, and diced vegetables. Typical capacity runs 500 to 5,000 kg per hour.\u003C/li>\n\u003Cli>\u003Cstrong>Belt tunnel.\u003C/strong> A straight belt carries product through several separately controlled temperature zones. It suits medium to large items such as shrimp, chicken portions, and cut fruit. Typical capacity runs 1,000 to 10,000 kg per hour.\u003C/li>\n\u003Cli>\u003Cstrong>Spiral.\u003C/strong> A helical belt climbs upward, saving floor area, and is chosen when product needs a longer residence time inside the tunnel. Available from small scale up to roughly 8,000 to 10,000 kg per hour.\u003C/li>\n\u003C/ol>\n\n\u003Cp>Energy use is not a rounding error. For a fluidised bed running green beans, refrigeration demand sits around 80 to 140 kW per tonne of product. That figure sets compressor capacity, and compressor capacity ends up setting how much insulation thickness makes economic sense.\u003C/p>\n\n\u003Ch2>When to Choose a Blast Freezer, and When to Choose IQF\u003C/h2>\n\n\u003Cp>The question is not which technology is more advanced. It is which one matches your product and your volume.\u003C/p>\n\n\u003Cp>Choose a blast freezer when product is large or cannot be separated, such as carcasses, whole fish, and fillet blocks. It also makes sense when daily volume is still uneven, when you run many product types in small batches, or when capital is tight. A single room handles a wide product mix without changing machinery.\u003C/p>\n\n\u003Cp>Choose IQF when pieces are uniform, when the market demands free-flowing retail packs, when daily throughput is consistent and high, and when texture quality sets your selling price. Note that IQF requires a continuous line upstream and downstream. The tunnel cannot stand alone without sorting, blanching, and packing running at the same rhythm.\u003C/p>\n\n\u003Cp>In practice many plants run both: IQF for high-margin flagship lines, and a blast freezer for the remainder of production plus raw material arriving off schedule.\u003C/p>\n\n\u003Ch2>Room and Panel Specifications That Get Overlooked\u003C/h2>\n\n\u003Cp>\u003Cimg src=\"https://assets.sandwichpanels.id/blog/1787083821859-iqf-vs-blast-freezer-panduan-2026-cover-01.png\" alt=\"IQF spiral freezer tunnel and blast freezer room built with insulated sandwich panels in a food processing plant\" />\u003C/p>\n\n\u003Cp>The machine usually gets specified first and the room follows afterwards. That order is why so many projects run energy-hungry from their first day of operation.\u003C/p>\n\n\u003Cp>PIR panels with thermal conductivity around 0.020 W/(m·K) come in thicknesses from 50 to 200 mm and hold up across a service range of -50°C to +80°C. For rooms below -20°C, 150 to 200 mm is the practical reference. U-value maths is simple, lambda divided by thickness, and freezer envelopes are generally aimed at 0.17 to 0.24 W/m²K.\u003C/p>\n\n\u003Cp>ASHRAE 90.1-2016 sets a minimum of R-32 for walk-in freezer walls and ceilings and R-28 for floors. Industrial facilities working in the -30°C to -40°C range normally exceed those minimums.\u003C/p>\n\n\u003Cp>Three items get missed on site more than any others:\u003C/p>\n\n\u003Cul>\n\u003Cli>\u003Cstrong>Frost heave in the floor.\u003C/strong> The soil under the slab freezes, the moisture in it expands, and the slab lifts by several centimetres over a few seasons. The fix is under-slab heating: an electric grid, a glycol loop, or recovered heat from the refrigeration system.\u003C/li>\n\u003Cli>\u003Cstrong>Joint airtightness.\u003C/strong> Properly sealed cam-lock or tongue-and-groove joints keep air leakage below 0.1 m³ per hour per m² at 50 Pa. A small leak means ice forming inside the panel, not merely a higher electricity bill.\u003C/li>\n\u003Cli>\u003Cstrong>Vapour barrier position.\u003C/strong> Water vapour always travels from the warm side toward the cold side. Put the barrier on the wrong face and the insulation wets out, losing R-value permanently.\u003C/li>\n\u003C/ul>\n\n\u003Cp>For small capacities or temporary needs, container-based freezer rooms can bridge the gap before a permanent facility is built. We covered the advantages and the limits in our \u003Ca href=\"https://sandwichpanels.id/en/blog/sandwich-panel-cold-storage-container-mobile-cold-room-2026\">guide to container cold storage and mobile cold rooms\u003C/a>.\u003C/p>\n\n\u003Ch2>The Indonesian Market Context in 2026\u003C/h2>\n\n\u003Cp>Investment in freezing capacity is climbing. Indonesia's cold chain logistics market is projected to grow from USD 7.19 billion in 2025 to USD 7.51 billion in 2026 according to the \u003Ca href=\"https://www.mordorintelligence.com/industry-reports/indonesia-cold-chain-logistics-market\" rel=\"nofollow\">Mordor Intelligence report\u003C/a>, with fish and seafood accounting for 42.25 percent of market share in 2025.\u003C/p>\n\n\u003Cp>Installed capacity still falls short. Industry data puts national cold storage at roughly 350,000 pallet positions, only about 3 percent of national requirements, with more than 200,000 additional pallet positions needed over the next three years. That shortfall explains the long queue for freezer construction in fisheries hubs.\u003C/p>\n\n\u003Cp>Coastal plants carry one extra variable that is routinely underestimated: corrosion. Sea air shortens the life of a panel's protective coating, which we address separately in our \u003Ca href=\"https://sandwichpanels.id/en/blog/sandwich-panel-anti-karat-tambak-pesisir-2026\">guide to corrosion-resistant panels for aquaculture and coastal sites\u003C/a>.\u003C/p>\n\n\u003Ch2>FAQ\u003C/h2>\n\n\u003Ch3>Is IQF always better than a blast freezer?\u003C/h3>\n\u003Cp>No. IQF wins for uniform pieces at high volume destined for retail packs. For carcasses, whole fish, or fillet blocks, a blast freezer is the better fit and far cheaper in both capital and operating terms. Many plants run both for different lines.\u003C/p>\n\n\u003Ch3>What panel thickness do IQF and blast freezer rooms need?\u003C/h3>\n\u003Cp>For rooms operating below -20°C, PIR panels of 150 to 200 mm are the common reference. The exact figure depends on design temperature, product load, local climate, and the target U-value. Finish the cooling load calculation before locking thickness into the drawings.\u003C/p>\n\n\u003Ch3>Can IQF replace cold storage?\u003C/h3>\n\u003Cp>It cannot. IQF is a freezing process, not a storage facility. Once product leaves the tunnel it still needs to be held at -18°C or colder under Codex CXC 8-1976. The two are built with different panel specifications and different refrigeration configurations.\u003C/p>\n\n\u003Ch3>Why does a freezer floor need heating?\u003C/h3>\n\u003Cp>Because the ground under the slab freezes and expands. Under-slab heating keeps soil temperature above freezing so the slab does not lift, racking stays plumb, and the floor does not crack. This component costs far more to retrofit than to install from the start.\u003C/p>\n\n\u003Cp>The sandwichpanels.id team handles IQF rooms, blast freezers, and cold storage from panel specification through installation. Send us your design temperature, daily capacity, and room dimensions for a thickness calculation and a panel quantity estimate.\u003C/p>","\u003Cp>Banyak pabrik pengolahan pangan di Indonesia memakai istilah \"blast freezer\" dan \"IQF\" seolah keduanya sama. Padahal keduanya menjawab masalah berbeda: satu membekukan muatan dalam tray, satu lagi membekukan butir demi butir. Salah pilih di tahap desain berarti salah investasi mesin, salah ukuran ruang, dan salah spesifikasi panel insulasi.\u003C/p>\n\n\u003Cp>Artikel ini membandingkan keduanya dari sisi angka teknis, jenis produk, dan konsekuensinya terhadap konstruksi ruang beku. Kami menulisnya sebagai pabrikan panel, jadi bagian yang jarang dibahas vendor mesin, yaitu dinding, lantai, dan kerapatan udara, ikut masuk ke dalam pembahasan.\u003C/p>\n\n\u003Ch2>Apa Bedanya IQF dan Blast Freezer?\u003C/h2>\n\n\u003Cp>Blast freezer atau air blast freezer (ABF) adalah ruang atau kabinet tempat produk disusun di tray dan rak, lalu dihembus udara dingin bersuhu sekitar -35°C hingga -40°C dengan kecepatan tinggi. Prosesnya batch: muat, bekukan, keluarkan, ulangi.\u003C/p>\n\n\u003Cp>IQF (Individual Quick Freezing) adalah proses kontinu. Produk berjalan di atas ban berjalan melewati terowongan bersuhu di bawah -35°C, dan setiap potong membeku terpisah sehingga tidak menggumpal menjadi blok. Hasilnya bisa dituang, ditimbang ulang, dan dikemas per porsi.\u003C/p>\n\n\u003Cp>Keduanya tunduk pada acuan mutu yang sama. Codex Alimentarius CXC 8-1976, diadopsi 1976 dengan revisi terakhir 2008, menetapkan produk quick frozen harus mencapai dan dipertahankan pada -18°C atau lebih dingin di titik pusat termal, di seluruh mata rantai dingin. Praktik SNI untuk ikan beku di Indonesia juga memakai -18°C suhu inti sebagai patokan.\u003C/p>\n\n\u003Cp>Ada satu hal yang sering tertukar di lapangan: -18°C itu target penyimpanan, bukan target pembekuan. Blast freezer dan IQF adalah cara mencapainya, sedangkan cold storage hanya mempertahankannya. Pemisahan fungsi ini kami bahas lebih rinci di \u003Ca href=\"https://sandwichpanels.id/blog/blast-freezer-vs-cold-storage-2026\">perbandingan blast freezer vs cold storage\u003C/a>.\u003C/p>\n\n\u003Ch2>Perbandingan Teknis: Kecepatan, Kristal Es, dan Drip Loss\u003C/h2>\n\n\u003Cp>Angka yang paling menentukan mutu adalah lama pembekuan, karena itulah yang menentukan ukuran kristal es di dalam jaringan produk.\u003C/p>\n\n\u003Cul>\n\u003Cli>\u003Cstrong>Waktu beku.\u003C/strong> IQF membekukan tiap potongan dalam hitungan menit, umumnya 3 sampai 15 menit tergantung ukuran. Blast freezer bekerja per muatan: fillet tipis 30 sampai 90 menit, blok udang sekitar 2 jam, dan potongan tebal atau muatan penuh bisa memakan beberapa jam. Rujukan waktu beku ikan dapat dilihat pada \u003Ca href=\"https://www.fao.org/4/v3630e/v3630e06.htm\" rel=\"nofollow\">dokumen FAO tentang freezing time in fisheries\u003C/a>.\u003C/li>\n\u003Cli>\u003Cstrong>Ukuran kristal es.\u003C/strong> Pembekuan lambat membentuk kristal di atas 100 mikrometer yang merobek dinding sel. Sistem IQF menghasilkan kristal di bawah 25 mikrometer, sehingga struktur sel relatif utuh.\u003C/li>\n\u003Cli>\u003Cstrong>Drip loss saat thawing.\u003C/strong> Produk IQF umumnya kehilangan 3 sampai 8 persen bobot, sedangkan produk beku blok 10 sampai 20 persen. Selisih itu setara penurunan susut 30 sampai 50 persen.\u003C/li>\n\u003Cli>\u003Cstrong>Bentuk keluaran.\u003C/strong> IQF menghasilkan butiran lepas yang siap ditimbang per kemasan. Blast freezer menghasilkan blok atau tray yang harus dipecah dulu sebelum dikemas ulang.\u003C/li>\n\u003C/ul>\n\n\u003Cp>Untuk eksportir udang atau buah potong, selisih drip loss langsung terbaca di neraca. Pada throughput 1.000 kg per hari, selisih susut 7 persen berarti 70 kg produk per hari yang berubah menjadi air di meja konsumen.\u003C/p>\n\n\u003Ch2>Jenis Mesin IQF dan Kapasitasnya\u003C/h2>\n\n\u003Cp>IQF bukan satu jenis mesin. Ada tiga konfigurasi yang lazim dipakai industri pangan, dan masing-masing menuntut bentuk ruang yang berbeda.\u003C/p>\n\n\u003Col>\n\u003Cli>\u003Cstrong>Fluidized bed.\u003C/strong> Udara berkecepatan tinggi mengangkat produk kecil sehingga membeku dalam keadaan melayang.

Kapasitas umum 500 sampai 5.000 kg per jam.\u003C/li>\n\u003Cli>\u003Cstrong>Belt tunnel atau terowongan sabuk.\u003C/strong> Ban lurus melewati beberapa zona suhu yang diatur terpisah. Cocok untuk produk sedang sampai besar seperti udang, potongan ayam, dan buah potong. Kapasitas 1.000 sampai 10.000 kg per jam.\u003C/li>\n\u003Cli>\u003Cstrong>Spiral.\u003C/strong> Ban berjalan melingkar naik sehingga hemat luas lantai, dipakai saat produk butuh waktu tinggal lebih lama di dalam terowongan. Tersedia dari skala kecil sampai sekitar 8.000 hingga 10.000 kg per jam.\u003C/li>\n\u003C/ol>\n\n\u003Cp>Konsumsi energi bukan angka kecil. Untuk fluidized bed dengan produk buncis, kebutuhan refrigerasi berkisar 80 sampai 140 kW per ton produk. Angka itu menentukan kapasitas kompresor, dan pada akhirnya menentukan seberapa tebal insulasi yang masuk akal secara ekonomi.\u003C/p>\n\n\u003Ch2>Kapan Pilih Blast Freezer, Kapan Pilih IQF\u003C/h2>\n\n\u003Cp>Pertanyaannya bukan mana yang lebih canggih, melainkan mana yang cocok dengan produk dan volume produksi Anda.\u003C/p>\n\n\u003Cp>Pilih blast freezer bila produk berukuran besar atau tidak bisa dipisah seperti karkas, ikan utuh, dan blok fillet. Blast freezer juga masuk akal ketika volume harian belum stabil, ragam produk banyak dengan batch kecil, atau anggaran investasi masih terbatas. Satu ruang bisa menangani banyak jenis produk tanpa perubahan mesin.\u003C/p>\n\n\u003Cp>Pilih IQF bila produk berbentuk potongan seragam, pasar menuntut kemasan retail siap tuang, throughput harian sudah konsisten dan tinggi, serta mutu tekstur menjadi pembeda harga jual. Perlu dicatat, IQF menuntut lini produksi kontinu di hulu dan hilirnya. Mesin ini tidak bisa berdiri sendiri tanpa sortasi, blansir, dan pengemasan yang seirama.\u003C/p>\n\n\u003Cp>Dalam praktiknya banyak pabrik memakai keduanya: IQF untuk lini produk unggulan yang bermargin tinggi, dan blast freezer untuk sisa produksi serta bahan baku yang masuk di luar jadwal.\u003C/p>\n\n\u003Ch2>Spesifikasi Ruang dan Panel yang Sering Dilupakan\u003C/h2>\n\n\u003Cp>\u003Cimg src=\"https://assets.sandwichpanels.id/blog/1787083821859-iqf-vs-blast-freezer-panduan-2026-cover-01.png\" alt=\"Terowongan IQF dan ruang blast freezer berdinding sandwich panel di pabrik pengolahan pangan\" />\u003C/p>\n\n\u003Cp>Mesin sering dipilih lebih dulu dan ruangnya menyusul belakangan. Urutan itulah yang membuat banyak proyek boros energi sejak hari pertama beroperasi.\u003C/p>\n\n\u003Cp>Panel PIR dengan konduktivitas termal sekitar 0,020 W/(m·K) tersedia pada ketebalan 50 sampai 200 mm dan bertahan pada rentang layanan -50°C sampai +80°C. Untuk ruang di bawah -20°C, ketebalan 150 sampai 200 mm menjadi acuan praktis. Nilai U dihitung sederhana, yaitu lambda dibagi tebal, dan ruang beku umumnya diarahkan ke kisaran 0,17 sampai 0,24 W/m²K.\u003C/p>\n\n\u003Cp>ASHRAE 90.1-2016 menetapkan minimum R-32 untuk dinding dan langit-langit walk-in freezer serta R-28 untuk lantai. Fasilitas skala industri yang bekerja di rentang -30°C sampai -40°C biasanya melampaui angka minimum tersebut.\u003C/p>\n\n\u003Cp>Tiga hal berikut paling sering luput dari perhatian di lapangan:\u003C/p>\n\n\u003Cul>\n\u003Cli>\u003Cstrong>Frost heave di lantai.\u003C/strong> Tanah di bawah slab ikut membeku, air di dalamnya mengembang, dan slab terangkat sampai beberapa sentimeter dalam beberapa musim. Solusinya pemanas bawah slab berupa grid listrik, loop glikol, atau panas buang dari sistem refrigerasi.\u003C/li>\n\u003Cli>\u003Cstrong>Kerapatan udara pada sambungan.\u003C/strong> Sambungan cam-lock atau tongue-and-groove yang tersegel benar menekan kebocoran udara di bawah 0,1 m³ per jam per m² pada tekanan 50 Pa. Kebocoran kecil berarti bunga es tumbuh di dalam panel, bukan sekadar tagihan listrik naik.\u003C/li>\n\u003Cli>\u003Cstrong>Posisi vapour barrier.\u003C/strong> Uap air selalu bergerak dari sisi hangat ke sisi dingin. Bila penghalang uap dipasang di sisi yang salah, insulasi menjadi basah dan nilai R-nya turun secara permanen.\u003C/li>\n\u003C/ul>\n\n\u003Cp>Untuk kapasitas kecil atau kebutuhan yang sifatnya sementara, ruang beku berbasis kontainer bisa menjadi jalan tengah sebelum membangun fasilitas permanen.

Data industri menyebut kapasitas cold storage nasional sekitar 350.000 posisi palet, hanya sekitar 3 persen dari kebutuhan nasional, dengan tambahan lebih dari 200.000 posisi palet yang dibutuhkan dalam tiga tahun ke depan. Angka itu menjelaskan kenapa antrean pembangunan ruang beku di sentra perikanan cukup panjang.\u003C/p>\n\n\u003Cp>Untuk pabrik di kawasan pesisir ada satu variabel tambahan yang kerap diremehkan, yaitu korosi.

IQF unggul untuk potongan seragam dengan volume tinggi dan kemasan retail. Untuk karkas, ikan utuh, atau blok fillet, blast freezer justru lebih tepat dan jauh lebih murah baik dari sisi investasi maupun operasi. Banyak pabrik memakai keduanya untuk lini yang berbeda.\u003C/p>\n\n\u003Ch3>Berapa ketebalan panel untuk ruang IQF dan blast freezer?\u003C/h3>\n\u003Cp>Untuk ruang yang beroperasi di bawah -20°C, panel PIR setebal 150 sampai 200 mm adalah acuan yang umum dipakai. Angka pastinya bergantung pada suhu desain, beban produk, iklim setempat, dan target nilai U. Perhitungan beban pendinginan harus selesai sebelum ketebalan dikunci di gambar kerja.\u003C/p>\n\n\u003Ch3>Apakah IQF bisa menggantikan cold storage?\u003C/h3>\n\u003Cp>Tidak bisa. IQF adalah proses pembekuan, bukan fasilitas penyimpanan. Setelah keluar dari terowongan, produk tetap perlu disimpan pada -18°C atau lebih dingin sesuai Codex CXC 8-1976. Keduanya dibangun dengan spesifikasi panel dan konfigurasi refrigerasi yang berbeda.\u003C/p>\n\n\u003Ch3>Kenapa lantai ruang beku perlu pemanas?\u003C/h3>\n\u003Cp>Karena tanah di bawah slab ikut membeku dan mengembang. Pemanas bawah slab menjaga suhu tanah tetap di atas titik beku sehingga slab tidak terangkat, racking tidak miring, dan lantai tidak retak.
