manufacturing freeze dryer preparation analysis
The manufacturing freeze dryer is an excellent drying method. Under the sealed condition, the dried product can be stored for a long time without additives at room temperature. The structure of freeze-dried products is porous and crisp, and the rehydration is fast when used. The color, fragrance, taste, shape and activity of the items after rehydration are basically unchanged. The vacuum freeze-dryer is particularly suitable for food, health care products and pharmaceutical industries. The manufacturing freeze dryer technology freezes the wet material or solution into a solid at a relatively low temperature (-10°C to -50°C), and then sublimates the water in a vacuum (1.3 to 13 Pa) without using a liquid state. Gaseous, dry technology that ultimately dehydrates the material. Technology is the core guarantee for corporate innovation and transformation, and quality is also the guarantee of product destiny. manufacturing freeze dryer manufacturers always adhere to the "quality of survival, efficiency and development," the company aims to dare to take the lead, and the courage to innovate, and strive to improve product quality, so as to better serve our customers.
When using the manufacturing freeze dryer for the first time, the components of the instrument must be thoroughly cleaned. The stainless steel parts should be cleaned with ethanol. The organic glass should be cleaned with normal saline. Ampoule bottles are cleaned with an ultrasonic cleaner.
Freeze-drying must be pre-frozen, want to move need to prepare a low-temperature refrigerator, minus 40 degrees Celsius, or minus 80 degrees Celsius refrigerator, put the items to be dried in a low-temperature refrigerator or liquid nitrogen, generally takes about four hours, Can be observed directly from the outside, after the article is completely frozen and frozen, the freeze-drying experiment can be carried out, and the articles are quickly moved to the manufacturing freeze dryer tray to ensure the freeze-drying effect.
The host and the vacuum pump are connected by a green vacuum tube. The connection uses international standard clamps. In order to effectively prevent the leakage of air, this type of clamp is specially designed with a sealing rubber ring inside the clamp. In the method of preventing air leakage, apply a proper amount of vacuum grease to the rubber ring, and then tighten the clamps to make the joints fit together more closely. If there is no clamping clamp, it will cause air leakage, resulting in the dashboard shows a digital display value greater than 20pa when the vacuum is drawn, this time you should check the airtightness of the vacuum pump and manufacturing freeze dryer glass cover.
There are two power sockets on the right side board of the manufacturing freeze dryer host. One is to connect the power cable of the vacuum pump to the host, and then the main power supply on the second manufacturing freeze dryer is plugged in.
Before the vacuum pump operates, it must be checked whether the vacuum pump oil is added or it will not operate normally. The oil level must not be lower than the midline of the oil mirror. When the vacuum pump is used at the beginning, it has a relatively strong jitter and slowly becomes smooth.
If the airtightness is not good, some vacuum grease should be applied to the sealing rubber ring above the cold trap, the organic glass cover should be lightly screwed on the rubber ring, and the airtightness of the manufacturing freeze dryer vacuum pump should be tested. To ensure the integrity of the manufacturing freeze dryer gas seal.

Manufacturing freeze dryer application range:
Food industry: Freeze dryers are often used for drying fruits and vegetables, meat and poultry, aquatic products, condiments, convenience foods and specialty products. Therefore, freeze dryers are also known as food freeze dryers to maintain the original color, aroma, taste and shape of food. The purpose of the freshness is unchanged, and the rehydration is good, the finished product is easy to store and transport, the cost is reduced, and the storage period is prolonged.
Medicinal health: in the drying of royal jelly, ginseng, turtles, cockroaches, cockroaches and other nutraceuticals, vacuum freeze-drying process, better preserve the original nutritional value, and make people believe that the nutritional products are pure and natural.
Pharmaceutical industry: used for dehydration and preservation of Chinese and Western medicines such as serum, plasma, vaccines, enzymes, antibiotics, and hormones.
Biological research: Long-term preservation of blood, bacteria, arteries, bones, skin, cornea, nerve tissue and various organs using vacuum freeze-drying technology, only need to supply water to regenerate when using, still maintain its physical properties
