reeze-drying introduction

Freeze dryer known as lyophilizer, is an especial machine to dry different types of material to prolong its preservation time. Among dozens of different dryers, freeze dryer is the best one to make high quality dried products. By freeze drying, product is heated after completely frozen, and the moisture in the product is ice status in the whole drying procedure till completely dried. Therefore, the freeze dried products preserve its original shape, color and flavor, and most importantly it has no biological activity loss, no nutrition loss.

Full range of freeze dryers provided: the small unit is for laboratory and home use; the medium-sized is for food and pharmaceutical drying application; the large-sized freeze dryer is for food and chemical industry which requires mass production with lower energy consumption.

Remarkable advantage of freeze-dried products

1, Retain biological activity

To retain biological activity as much as possible, the material must be in low temperature environment, but on the contrary, drying needs heat involved. Heating will destroy biological activity and nutrition. Our solution is to get the liquid water in the material completely frozen to solid status. The water in the material is solid ice status during the whole heating processing till the material is completely dried. So, the biological activity is retained greatly.

2, No damage to the nutrition

Heating is no doubt the main reason of nutrition damage. By using our freeze dryer, heating processing occurs after material gets completely frozen to ice status. Thus, it typically retains 97% of the nutritional value.

3, Taste, color and appearance

Lyophilized by our freeze dryer, the material still tastes fresh, delicious as a snack, but a different try. The freeze dried material remains the same color, flavor and appearance as it was firstly harvested. And the volume of freeze dried material has no change, that is to say the appearance has no shrink or toughen. It is the real high quality preserved food.

4, FD-1000 microwave High quality freeze dryer shelf-life

Freeze dried food material has a FD-1000 microwave High quality freeze dryer preservation time than frozen food, canned food and oven drying food. Having freeze dried food storage, you do not need to rack your brains what to eat and far away from pigmentum, additive, GMO and anti-season food material. Freeze-drying help us design a healthy lifestyle.

microwave dryer advantages of equipment

1, microwave dryer, short, fast

Conventional thermal sterilization is used to transmit heat from the surface of the food to the interior through heat conduction, convection, or radiation. It often takes a long time to get the germicidal temperature. The FD-1000 microwave High quality freeze dryer is the direct interaction between microwave energy and microorganisms such as food and bacteria. The interaction between heat effect and non thermal effect can achieve fast warming and bactericidal action, and the processing time is greatly reduced. The sterilization effect of various materials is usually 3-5 minutes.


2, FD-1000 microwave High quality freeze dryer low temperature sterilization keep the nutrition and traditional flavor The FD-1000 microwave High quality freeze dryer is through special heat and non thermal effect sterilization, compared with conventional thermal sterilization, it can get the desired disinfection effect at relatively low temperature and short time. Practice shows that the general sterilization temperature can reach the effect at 75-80 degrees centigrade. In addition, microwave dryer processed foods can retain more nutrients and color, aroma, taste, shape and other flavors, and have puffing effect. For example, the vitamin C retained in vegetables treated by conventional heat treatment is 46-50%, while that in microwave treatment is 60-90%, while that in conventional heating is 58%, while that in microwave heating is 84%.


3 microwave dryer and FD-1000 microwave High quality freeze dryer save energy Conventional thermal sterilization often has heat loss in the environment and equipment, and microwave is directly treated to food, so there is no extra heat loss. In addition, the conversion efficiency of the electric energy to the microwave energy is in the 70-80%, and the power is generally reduced to 30-50%.
