Kassel Large Freeze Drying Machine

The Kassel large-scale freeze dryer is a drying method that utilizes the sublimation principle to preserve the original color, aroma, taste, shape, and nutritional components of food without significant changes. There are many varieties, high yields, and rich nutrients of tropical fruits. Currently, the FZG food freeze-drying machine integrated system is used for processing mango freeze-drying, red dragon jelly drying, banana freeze-drying, pineapple freeze-drying, lemon freeze-drying, and other tropical fruit vacuum freeze-drying applications, promoting the development of deep processing of tropical fruit freeze-drying and driving the local economy!

1. Wide applicability and multiple types of finished products

Traditional cold storage freeze-drying machines are generally suitable for low-end food processing (products with low quality requirements), while new food freeze-drying equipment can process almost all agricultural products, with a variety of finished products. Vegetables such as spinach, celery, coriander, and yellow flowers, fruits such as dates, bananas, kiwis, and bayberries; Aquatic products such as sea cucumbers, turtles, and kelp; Condiments such as scallions, ginger, and garlic; Beverages such as coffee, tea, chrysanthemum, wolfberry, and bird's nest; Chinese medicinal herbs such as Dendrobium, Cordyceps, and Snow Lotus; And agricultural products with strict requirements for active ingredients (royal jelly freeze-dried powder, sea buckthorn jelly dry powder) can be processed. The finished products include freeze-dried fruits and vegetables, freeze-dried meat, freeze-dried instant noodles, freeze-dried soup Congee, instant drinks and many other products.

2. High quality processed agricultural products

Vacuum freeze-drying, with its advanced processing technology, produces agricultural products of much higher quality than those processed through other food processing methods. Studies have shown that freeze-dried chestnut powder contains starch, protein, reducing sugars VC、 The tannin content was significantly higher in chestnut flour processed by natural ventilation drying, hot air drying, microwave drying, and microwave vacuum drying; The freeze-dried jujube slices have good appearance quality, high sugar and flavonoid content, and good texture; The water loss rate and rehydration rate of the glutinous rice instant Congee processed by the method were significantly higher than those of vacuum drying and hot air drying. In addition, the processed agricultural products also have advantages such as small size, light weight, easy transportation, and long shelf life.

3. Significant increase in added value of agricultural products

China is a major producer and consumer of agricultural products. In 2018, the total output of meat in China was 85.17 million tons, with a total consumption of 88.296 million tons, and the total output of vegetables was 703.47 million tons, with a total consumption of 692.71 million tons. However, China's agricultural products are mainly consumed directly or through rough processing, with a much lower proportion of deep processing compared to developed countries such as the United States and Japan, resulting in low added value of agricultural products. Vacuum freeze-drying can significantly increase the added value of agricultural products, with profits reaching over 60%

4. Freeze dried agricultural products can lock in costs.

Due to the advantages of ultra long shelf life and ultra-low storage cost (room temperature storage) of freeze-dried agricultural products. No matter how agricultural products change in the future, the cost of freeze-dried agricultural products during their shelf life is basically fixed. Even if it's just buying it and eating it for oneself, it's still profitable.

5. Freeze dried agricultural products have the potential for appreciation.

Tropical fruits are rich in nutrients such as dietary fiber due to their high calorie content and photosynthesis caused by abundant rainfall and light in the south. At present, deep processing enterprises are limited to processing dried fruits, canned goods, fruit juice, etc., which have problems such as short storage time, the need to add various additives, loss of nutrients, and high transportation and storage costs. A food freeze dryer uses the principle of sublimation in a high vacuum state to remove the moisture in pre frozen tropical fruit samples without melting the ice, directly sublimating them into water vapor in an ice state to achieve the purpose of freeze-drying tropical fruits. The growth of microorganisms and the action of enzymes at low temperatures are almost impossible to carry out, with protein invariance and protection of microorganisms and other microorganisms. The loss of volatile components, heat denatured nutrients, and aromatic components in fruits is minimal, and after drying, they maintain their original characteristics in a porous sponge shape, so the nutrients are preserved, and their shape and color remain basically unchanged. They have the advantages of good rehydration, minimal water content, and can be stored for a long time at room temperature, solving the problems of traditional deep processing.

Kassel large-scale freeze-drying machines are widely used in tropical fruit freeze-drying processing. According to the working principle of food freeze-drying machines, they are also suitable for deep processing applications such as subtropical fruit freeze-drying and northern fruit freeze-drying, providing natural, nutritious, and additive free freeze-dried fruit food. Addressing the issues of nutrient loss, high storage and circulation costs in traditional processing.
