What Are the Application of Quick Freeze Evaporator in Food Processing?

Meat Processing Field

Fresh meat quick-freezing: In the processing of pork, beef, lamb and other fresh meat, quick-freezing evaporator plays a key role. Freshly slaughtered meat requires rapid cooling to inhibit microbial growth and enzyme activity. For example, an evaporator can quickly freeze fresh pork from room temperature to below -18°C. The entire process may take only a few hours, depending on the volume of the pork and the performance of the evaporator. This effectively extends the shelf life of the meat while maintaining its tenderness and nutrient content.

Quick-freezing of meat products: Quick-freezing evaporators are also indispensable for processed meat products such as sausages, hams and meatballs. These meat products need to pass through the maximum ice crystal generation zone quickly after production to prevent ice crystals from damaging their tissue structure. For example, when quick-freezing meatballs, an evaporator can reduce the center temperature of the meatballs to around -18°C in 15 - 30 minutes, ensuring that the meatballs maintain their good taste and quality during subsequent storage and transport.

Fish Processing Industry

Fish quick-freezing: In fish processing, quick-freezing evaporators can quickly lock in the freshness of fish. Both saltwater and freshwater fish need to be frozen as soon as possible after being caught. For example, like salmon, a fish with high quality requirements, the evaporator can reduce its temperature to - 20 ℃ - 25 ℃ in a short period of time, reducing the oxidation and deterioration of the fish body, and maintaining the color and taste of the fish.

Shrimp and shellfish quick-freezing: for shrimp and shellfish products, quick-freezing evaporator can quickly reduce its temperature to prevent protein denaturation of shrimp and shellfish. Take shrimp as an example, the evaporator can reduce the center temperature of shrimp to about -18℃ in 20-30 minutes, so that the shrimp still retains its elasticity and freshness after thawing. For shellfish, such as scallops, oysters, etc., the quick-frozen evaporator can also effectively maintain their tender taste and rich nutrition.

Fruit and Vegetable Processing

Whole fruit quick-freezing: In fruit processing, quick-freezing evaporator can be used for whole fruit quick-freezing, such as strawberries, blueberries, cherries and so on. After picking, these fruits can be quickly frozen through the quick-freezing evaporator, thus retaining the vitamins, minerals and antioxidants and other nutrients in the fruits. For example, quick-freezing strawberries can reduce the center temperature to about -18℃ in 10 - 20 minutes, and the color of the quick-freezing strawberries is bright, and the original taste and flavor can be better maintained after thawing.

Vegetable quick-freezing: for vegetables, quick-freezing evaporator is also widely used. For example, in the quick-freezing of broccoli, beans, carrots and other vegetables, the evaporator can quickly reduce the temperature of the vegetables to - 18 ℃ - 20 ℃, inhibit the respiration of vegetables and the growth of microorganisms. This allows vegetables to maintain their freshness and nutrition after long-term storage, and better restore their original texture when cooking.

Baked Foods and Prepared Vegetables Processing

Baked goods quick-freezing: in the processing of baked goods such as bread, pastries, etc., quick-freezing evaporators can be used for the rapid freezing of products. Some bakeries will quick-freeze freshly baked bread in order to ensure the freshness of their products. For example, French baguette bread is baked and then the center temperature is lowered to about -18°C in 30 - 45 minutes by a quick-freeze chiller, so that the taste and aroma of the bread can be better preserved during subsequent storage, and the consumer can thaw and consume the bread after purchase.

Prepared vegetable quick-freezing: With the development of the prepared vegetable industry, the role of quick-freezing evaporator is more prominent. For all kinds of prepared dishes, such as Kung Pao Chicken, Shredded Pork with Fish, etc., after processing, they need to be quickly frozen by quick-freezing evaporator, so that the dishes can reach the required low temperature in a short time to maintain the color and flavor of the dishes. The quick-frozen prepared dishes can be easily stored and transported to meet consumer demand.

Dairy and Bean Products Processing

Dairy quick-freezing: In some special dairy products processing, such as cheese and milk jelly, quick-freezing evaporator can be used for rapid molding and freezing of the products. For example, when making cheese, the quick-freezing evaporator can help the cheese to solidify and reduce the temperature in a short time, so as to maintain its delicate texture and unique flavor.

Soybean products quick-freezing: For soybean products, such as tofu and soybean skin, quick-freezing evaporators are also used. Take quick-frozen tofu as an example, the cold evaporator can quickly lower the temperature of the tofu to make its internal structure firmer, and it can still maintain a certain degree of elasticity after thawing, which is easy to cook and eat.
