醫藥冷庫之速凍是一種快速凍結的低溫保鮮法。所謂冷庫速凍果蔬，就是將經過處理的果蔬原料，采用快速冷凍的方法，使之凍結，然后在-18°c～-20°c的低溫下保存待用。

Quick freezing is a quick freezing and low temperature preservation method. The so-called cold storage frozen fruits and vegetables, that is, the processed fruits and vegetables raw materials, frozen by rapid freezing method, and then at -18 degrees C ~ -20 degrees C storage at low temperature stand-by.

速凍保藏，是當前果蔬加工保藏技術中能最大限度地保存其果蔬原有風味和營養成分較理想的方法。

Quick freezing preservation is the most ideal method to preserve the original flavor and nutritional components of fruits and vegetables at present.

一、選料

First, the choice of materials

加工速凍果蔬的原料要充分成熟，色、香、味能充分顯現，質地堅脆，無病蟲害、無霉爛、無老化枯黃、無機械損傷的果蔬作加工原料，最好能做到當日采收，及時加工，以保證產品質量。

Processing quick-frozen fruit and vegetable raw materials to fully mature, color, aroma and taste can fully show, firm crisp texture, no pests, no mildew, no aging, no mechanical damage of the yellow fruits and vegetables as raw material, it is best to do on the day of harvest, timely processing, to ensure the quality of products.

二、預冷

Two, precooling

剛采收的果蔬，一般都帶有大氣熱及釋放的呼吸熱。為確保快速冷凍，必須在速凍前進行預冷。其方法有空氣冷卻和冷水冷卻，前者可用鼓風機吹風冷卻，后者直接用冷水浸泡或噴淋使其降溫。

Freshly harvested fruits and vegetables usually carry the heat of the atmosphere and release the heat of the breath. In order to ensure quick freezing, pre cooling must be done before freezing. The method has air cooling and cold water cooling, the former can be blown and cooled by a blower, and the latter is directly cooled by cold water or sprayed to cool down.

冷庫 三、清洗

Cold storage three, cleaning

采收的果蔬一般表面都附有灰塵、泥沙及污物，為保證產品符合食品衛生標準，凍結前必須對其進行清洗。尤其是速冷果蔬更應如此，因為速凍制品食用時不再清洗，所以此次清洗非常重要，萬萬不可疏忽大意。洗滌除了手工清洗，還可采用洗滌機(如轉筒狀、振動網帶洗滌機)或高壓噴水沖洗。

The fruits and vegetables are usually covered with dust, sediment and dirt. In order to ensure that the products meet the food hygiene standards, they must be cleaned before freezing. Especially the rapid cooling of fruits and vegetables should be more so, because eating quick-frozen products no longer clean, so the cleaning is very important, must not be careless. In addition to hand washing, washing machines can be used (such as drum, vibration nets belt washing machine) or high-pressure water jet washing.

四、切分

Four, segmentation

速凍果蔬有的需要去皮、去果柄或根須以及不能用的籽、筋等，并將較大的個體切分成大體一致，以便包裝和冷凍。切分可用手工或機械進行，一般蔬菜可切分成塊、片、條、段、絲等形狀。要求薄厚均勻，長短一致，規格統一。漿果類的品種一般不切分，只能整果冷凍，以防果汁流失。

Frozen fruits and vegetables some need to peel and fruit stem or roots and can not be used for seed, bar and so on, and the larger individuals cut into roughly the same, so that the packaging and freezing. Segmentation can be done manually or mechanically, and vegetables can be cut into blocks, sheets, strips, sections, and filaments. Requirements of uniform thickness, the length of the same specifications. Berries are generally not segmented and can only be frozen whole fruit to prevent juice loss.
