What is IQF freezing? IQF meanings, fast-frozen principles and traditional refrigeration

食品加工與冷鏈產業的競賽，

本質上是一場「時間與溫度」的拉鋸戰。

In more than 20 years of customer service, the top of the roof has found that most generations of factories are facing a loss of Maori.It's all about the "hidden formation of the traditional freezer."

When traditional cold-freezing banks are no longer able to meet the stringent requirements of modern chemical plants for production capacity, probabilities and food security, the introduction of more advanced cold-freezing technologies is the only solution for breaking through the production bottle and raising Maori.

What does IQF mean? ♪ Quick freeze ♪

IQF Individual Quick Freezing means "one rapid, fast freezing."It is based on the use of very low temperatures and high-speed air currents below -35°C to allow food products (such as seafood, meat, vegetables) to stand alone through the largest ice-crystal generation belt in a few minutes. This is an effective way to prevent food blocks from stickling, locking water and reducing the defrosting rate to less than 1%.

Instead of placing large amounts of food in boxes and stacking on cars into cryogenic colds, the IQF technique is to make every shrimp, every blueberry, every piece of meat or every water plume frozen in a stand-alone state, in a very short period of time through a low-temperature wind hole, or a speed belt.

對於廠長與生產線主管而言，

IQF 解決了加工廠最頭痛的「結塊問題」。

Under very low temperatures (usually -35°C to -40°C or even lower) and high-speed air currents, surface moisture is immediately solidified, and the food is completely non-obedient. This means that back-end measurements, distributions, and packages can directly lead to fully automated devices. A consumer or a B2B customer can also "take as much as you want" without having to take the whole block back.A major increase in the commercial value and accessibility of products.

Which industries need IQF technology most? I've seen a lot of scenery for you!

IQF technology is not an exclusive industry.

IQF is an excellent application for IQF, as long as your products are equipped with "high economic value", "fear of the knot" or "focus on the post-frozen taste":

• Aquaculture:
  Shrimps, shrimps, dried beaks, scabs, fresh fish slices.
  IQF avoids shrimp and seafood surface frosting, and maintains a bright and bright velvet after the thaw.
  
• This is not the case.
  Beans, corn grains, broccoli, blueberries, mangotine.
  Freezing at extreme speed can lock down chlorophyll and phyll and avoid the thawing of vegetables.
  
• Meat and poultry processing:
  Chicken, meatballs, dice, burgers. Make sure the gravy isn't lost, keeps the meat bullety and sweet.
  
• Food and bake:
  Aqueducts, buns, frozen noodles, microwave ready-to-eat packs.
  It is perfect to protect yeast activity in the pasta and prevent the growth of bacteria during the cooling process.

Dismantling fast-frozen principles: the final battle "Maximity Crystal Generation Belt"

In order to understand why IQF can successfully lock up the freshness of food, it has to be explored from a food science perspective.Speed freeze.。

The key to the technology, it's on temperature. 0°C to -5°C Area.

The physical system of the biggest crystals.

In nature, most foods fall between 60% and 90%.

When the temperature of the food dropped to 0°C, the internal water began to freeze.

But when the temperature continues to drop to -5°C, about 80% of the free water inside the food will turn into crystals. According toFood and Agriculture Organization of the United Nations (FAO) Refrigeration Technology GuideThe food science community defines this area as the "Maximity Crystal Generation Belt".

At the heart of the fast-frozen principle is:

Using a strong cooling system and currents, using the most violent cooling speed, force the food to kill in seconds.。

The deadly difference between microcrystals and big ice crystals.

The slow rate of cooling directly determines the physical shape of water molecule ice.

This is also the most important indicator of "student reduction" and "cell integrity" for product protection and development:

• Slow cooling (traditional freeze):
  Water molecules have plenty of time to move and aggregate in their cells, and eventually to form large, sharp and irregular "black crystals".
• Extreme cooling (IQF fast freezing):
  Temperatures are so fast that water molecules can't get to one another, they can only freeze in situ in an instant, and form a "microcrystal" that is numerous but very small in size.
  

Water molecules and scavengers.

Plant cells are equipped with hard cell walls, and animal cells have fragile cellular membranes.

When the traditionally frozen large crystals break through and pierce these cells like blades, the eye tends to see no difference at the moment of freezing. However, once the product enters the final consumer's kitchen or restaurant and starts to defrozen, the ruptured cells are unable to lock the water, leading to a significant loss of juice, water soluble vitamins and flavors (known as "blood water" or "freeze water").

根據碩頂科技的建廠實測數據：

一般的工業用傳統冷凍庫要將產品結冰，最快也需要耗時 3 至 4 個小時。而採用碩頂 IQF 設備，以常見的小湯圓或湯包為例，僅需約 20 分鐘即可完成極速凍結；即便是體積較大、整袋包裝的山東大饅頭，也只需約 90 分鐘即可完成。IQF 設備透過鋁鰭片包覆銅管冷排與高壓風機，在幾十分鐘內讓產品中心溫度瞬間貫穿 -5°C 最大冰晶生成帶，時間效率相差高達 10 倍以上。

And the resulting microcrystals are round and small, and they preserve the cell structure perfectly.

Common IQF equipment type: tunnel and spiral

In order to achieve the effect of "one-size-size-fits-all cooling", IQF equipment is currently available in two main mainstream types.

You can choose according to the spatial and product characteristics of the plant:

1. Tunnel Freezer:
   The food is flat on the net and straight through the cold tunnel.
   適合扁平、重量較輕或需要短時間凍結的產品
   （例如：肉片、水餃）。
   The advantage is that the structure is simple, but the disadvantage is that the occupied plant is very long.
   
2. Spiral Freezer:
   Take a 3D spiral to the top of the belt.
   適合體積較厚、需要較長凍結時間的產品
   （例如：全雞、大塊肉類、調理包）。
   The greatest advantage isExtremely high plant., to exchange the smallest land-tenure for the largest continuous capacity.

Compared to traditional freezing: depth analysis of five major business assessment points

In order to enable you to further evaluate the value of the investment in the equipment,

The following is a five-dimensional comparison of IQF with the traditional freezer.

Evaluation point	Traditional freezer	IQF, speed freeze.
Frozen Mode and Status	Static, stacked and stored. It's a natural confrontation with cold air. The product can easily crush each other and needs to be broken.	Motivated, high-speed cold-winds are packaged in all directions through the delivery belt or fluid bed. It's clean, it's unmistakable, it's not sticky.
Over the crystal time.	It takes 3 to 4 hours It's easy to form big ice crystals that destroy cells.	最快僅需 20 分鐘（視體積而定，大體積如包裝饅頭約 90 分鐘） (Only round tiny crystals of ice).
Unfrozen weight loss rate	Extremely High (5% – 15%)。細胞破裂導致珍貴汁液與重量大量流失。	極低 (通常小於 1% – 2%)。完美鎖水，保留產品出廠重量與風味。
產能與廠房動線	批次處理，需佔用大量空間停放台車，且需大量人工搬運。	連續式生產，直接對接前處理線與後端包裝機，實現高度自動化。
食安與生菌數控制	降溫慢，中心溫度遲遲降不下來，增加微生物繁殖風險。	瞬間凍結，立刻阻斷酵素活性與微生物生長，輕鬆符合 HACCP 規範。

解凍失重率：吃掉企業利潤的「隱形成本」

對於肉品加工或高價水產而言，重量就是營收。

場景試算：

假設一間水產加工廠每月處理 100 噸的高單價蝦類：

使用傳統冷凍，解凍失重率若高達 8%，等於客戶買到 100 噸的產品，解凍後只剩 92 噸，流失的 8 噸全是高價值的鮮甜肉汁。這不僅引發 B2B 客戶客訴，更等於每月蒸發了數百萬元的潛在營收。

若導入 IQF 設備將失重率降至 1%，每個月等同於「救回」了 7 噸的產品價值。這筆省下的隱形成本，往往在一到兩年內就能完全攤平 IQF 的硬體採購費用。

破除迷思：IQF 設備一定比較耗電嗎？

滿多企業主擔心 IQF 的高壓風機導致電費暴增。

事實上，碩頂科技在設計 IQF 系統時，特別導入了「變頻風速控制」與「獨家風力內循環層流系統」，不僅能讓冷風均勻包裹食材秒殺冰晶帶，更大幅拉長了連續運轉時間、延緩結霜。比起傳統冷凍庫壓縮機 24 小時滿載運算，單位產能的能耗反而更低。

傳統冷凍庫因為降溫極慢，壓縮機必須長時間滿載運轉，且員工頻繁開關庫門會造成大量冷能流失。

先進的 IQF 設備搭配變頻技術與優化的風力內循環層流系統，能在最短時間內完成凍結任務。雖然初期建置成本較高，但長期運作下來的單位能耗卻能有效降低，符合企業 ESG 節能減碳的佈局。

食安稽核與自動化清潔

傳統冷凍庫降溫緩慢，食材中心溫度停留在「危險溫度帶（7°C ~ 60°C）」的時間過長，極易造成生菌數與大腸桿菌超標。

專業的 IQF 設備不僅能瞬間凍結微生物活性，全機更採用 SUS304 不鏽鋼打造，並可選配 CIP（Clean-in-Place）自動清洗系統，確保無死角清潔，幫助廠房輕鬆應對 ISO 222000 Food Safety Management System 或 衛福部 HACCP等國內外嚴格的食安稽核標準。
