The shelf temperature of the silicone oil heating freeze dryer is adjustable, controllable, explorable, pilot-scale and production process; 20 programs can be stored, each program can be set to 36 segments, the program parameters can be modified during operation, and the drying curve can be recorded ;touch screen operation, PID control, display drying curve; square tray is not easy to deform, easy to operate, easy to clean; equipped with air valve, can be filled with dry inert gas; the drying room adopts colorless transparent plexiglass door with high light transmission, which can be used in the operation process. Clearly observe the changing process of materials. The main features of silicone oil heating freeze dryer: The pre-freeze-drying is carried out in situ, with a built-in observation window, and the drying process is intuitive and controllable. The drying room temperature difference is less than or equal to 1℃, and the drying effect is uniform. The temperature of the partition is adjustable and controllable. The pilot test and production process can be explored. Because the drying chamber and the cold trap are separate structures, the water trapping ability is strong and the drying time is short. Equipped with an inflatable valve, which can flush out the inert gas. The drying room adopts aviation acrylic high-transparent transparent colorless door, and the change process of the material can be clearly observed during the freeze-drying process. The pre-freeze drying is carried out in situ, which reduces the tedious operation of the drying process and realizes automation. Embedded touch screen, PLC controller, PID adjust temperature, display freeze-drying curve and historical curve. Transfer data to U disk. Equipped with uploader software, which can print and browse curves and data.
Fruit and vegetable freeze drying equipment is the best way to produce high quality dehydrated food. The principle is to use the sublimation principle in the vacuum form, so that the moisture in the items that are frozen after the ice can not be sublimated into the water vapor by the ice, thus drying the material, which is called the freeze-drying equipment of fruit and vegetable, and the title freeze dry. The food produced in this way is called freeze-dried food. The future of fruit and vegetable freeze drying equipment is equally good, at least in the country. It is called the freeze drying equipment for fruits and vegetables, which is to freeze the moisture outside the vegetables, sublimate them, and finally reach the drying process. Early, because the profit of the fruit and vegetable freeze-drying equipment is high, the normal use is only used for special cause, such as navigation, investigation and other people, because of the comparative convenience, do not need special facilities to cook. Normal people will not be able to afford it. The money has not been bought in the market indirectly. At the same time, with the improvement of the skill level, the profit of the fruit and vegetable freeze drying equipment is getting lower and lower, so the price that is sold is becoming more and more common, and the normal people are able to bear it. The point of strength is storage unless the hygiene problem is concerned, and the rest do not ask for food, especially when it is convenient. A top priority is that the country is a great agricultural country, with all kinds of vegetables and abundant varieties of vegetables. If the Department is processed and transported to all parts of the country, the prospects for development are equally good. It is a dangerous and costly business work.
The pet food freeze dryers is based on the three-state change of water. Water has solid, liquid and gaseous states, and the three states can be transformed into each other and coexist. When water is at the triple point (temperature is 0.01°C, water vapor pressure is 610.5Pa), water, ice, and water vapor can coexist and balance each other. Under the high vacuum state, using the principle of sublimation, the moisture in the pre-frozen material can be directly sublimated into water vapor in the ice state without melting the ice, so as to achieve the purpose of freeze drying. The pet food freeze-drying machine has been developed and processed for chicken breast freeze-dried, beef freeze-dried, fish and shrimp freeze-dried, yogurt block freeze-dried, egg yolk freeze-dried, etc. At the same time, it can develop cat treats and functional cat food freeze-dried development. The loss of volatile components and heat-denatured nutrients and aromatic components in the cat food material of the dryer is very small, the protein is not denatured, and the microorganisms are not inactivated, so the nutrients are preserved. At present, freeze-dried cat food has been popular in the market, replacing traditional cat food products and bringing health to people. Nutritious, safe cat food, and super convenient. The pet food freeze-drying machine has been applied in the development and processing of cat food freeze-drying, and at the same time in the development and processing of various pet food such as dog food freeze-dried, bird food freeze-dried, rabbit food freeze-dried, fish food freeze-dried and other development and processing applications.
According to international standards, probiotics need to be active, have a sufficient number of microorganisms that are beneficial to the host, and can be called probiotics. Therefore, activity is the key to probiotics. After passing through the human digestive tract environment and successfully passing through gastric acid, bile, etc., the bacteria that can survive can reach the large intestine to play a role, and it is effective to contain at least 1 million bacteria. Because probiotics are very sensitive to heat, it is determined that probiotics can only be dried and processed by freeze-drying equipment. The freeze-drying technology can reduce the damage of probiotic biological tissues and cells, structures and characteristics, thereby protecting the stability of the active ingredients of dry heat-sensitive products such as probiotics. Ensure nutrient content and microbial preservation
Scope of application: It is suitable for drying heat sensitive raw materials that can decompose and polymerize and metamorphose at high temperature .It is wide used in pharmaceutical, chemical, foodstuff electronic industries. Please find the video at https://www.youtube.com/watch?v=4Fbi_zj_qpE&feature=youtu.be Principle: Vacuum drying is to put raw material under the state of vacuum for heating and drying. If use vacuum to pump air and humidity out, the dry speed will be faster. Note: if use condenser, the solvent in raw material can be recovered. If the solvent is water, condenser might be canceled and the investment and every could be saved. It use SK series water ring vacuum pump sets, condensate can not be used and the investment could be saved. Features: Under the condition of vacuum, the boiling point of raw material will decrease and make the pushing force become greater. Therefore for a certain amount of heat radiation, the conducting area of evaporator can be saved. The heat source for operation of evaporation may be low pressure steam or surplus heat steam or hot water The heat loss of evaporator is less; Before drying, the treatment of disinfection may be carried out. During the period of drying, there is no impurity material. It is in conformity with the requirement of GMP; It belongs to static drier. So the shape of raw material to be dried can not be destroyed.
