The drying box is also known as "oven" and "oven". According to the type of drying box, it can be divided into ordinary drying box, blast drying box and vacuum drying box .
Drying boxes are used in various industries such as chemical, pharmaceutical, casting, automotive, food, machinery, etc. Generally divided into galvanized steel and stainless steel liners, pointer and digital display, natural convection and blast circulation, conventional oven and vacuum type.
Next, some questions that people often encounter during the use of the drying oven will be answered by the brainstorming instrument.
First, why does the drying oven not heat?
A: Under normal circumstances, there may be problems with the temperature controller, electric heating tube and fan:
1. Measuring the temperature controller output;
2. Measure the resistance of the heating tube;
3. Does the fan turn?
Second, what is the difference between the blast drying box and the vertical?
A: The preferred appearance is that the difference between the desktop and the vertical is that one is floor-standing and the other is horizontal.
1) The vertical oven and bench-top oven meters are located at:
a. The instrument of the vertical oven is under the cabinet (if the customer puts the instrument on the top, it is also OK).
b. The instrument of the desktop oven is on the left side of the box. The vertical oven and the desktop oven have the same function, that is, the structure is not the same.
2) The positions of the vertical oven and the table oven fan are:
A, vertical oven can be according to national standards (±2%) because the air duct structure is special, the fan is at the bottom of the box, natural air convection.
B. The fan of the table oven is behind the box, forcing air convection.
3. What is the difference between a vacuum drying oven and a blast drying oven?
A: Vacuum drying ovens and blast drying ovens are two drying equipments we use. We know that to dry the dry material, it is only by direct heating, vacuuming and vacuuming to achieve the purpose of drying. However, where is the difference between the two?
Through the direct heating method, of course, there is also a blast-assisted air assisting method, which is to make the material get the material quickly by moving the moisture, solvent or volatile component molecules in the material to make the molecules move quickly to get rid of the dry material. dry. Its drying speed can be very fast and the drying temperature can be very high.
In particular, the blast drying box, under the action of the fan, rapidly removes the volatile substance molecules volatilized from the surface of the material by air exchange, thereby achieving the function of rapidly drying the material.
The vacuum drying oven draws the space where the dry material is located into a vacuum by a vacuum pump, that is, a vacuum state. It is known that in a vacuum state or a low pressure state, the boiling points of moisture, solvent and other volatile components in the material are lowered, so that at a lower temperature, the surface of the material particles can be removed from the surface of the material particles and evacuated by a vacuum pump. It is mainly used in materials that oxidize, polymerize and other chemical reactions at high temperatures. Of course, it also has the dual effect of heating to accelerate the evaporation of moisture, solvent and volatile components from the surface of the material.
The difference between the application of the two is the stability of the chemical properties of the object of the user's dry material and the physical deformation of the dry material.
4. What should I pay attention to when operating the blast drying oven?
Answer: 1. The outer casing of the drying box must be effectively grounded. After use, the power should be turned off to ensure safe use.
2. The drying oven should be placed in a well-ventilated room with no flammable or explosive materials placed around it.
3. Do not over-extrude the contents of the drying box, and make room for hot air circulation.
4. The drying box has no explosion-proof device and should not be placed in the flammable and explosive materials to ensure the safety of use.
5. Consumables such as seals, hot air motors, heating pipes, handles, etc. should be regularly maintained to clean dust.
6. It is not suitable for high voltage, high current, strong magnetic field, corrosive gas (such as acid, alkali, sulfur), so as not to interfere with damage and danger.
7. It is necessary to do the routine maintenance work of the drying box. The use and maintenance should be carried out by a full-time staff. The power must be cut off during maintenance to ensure safety.
8. Always keep the inside and outside of the box clean. Do not cover the plastic dust cover for a long time and put it in a dry room.
5. When using the drying box , set the temperature. After the temperature is reached, what is the working condition of the drying box?
A: After the temperature is reached, the drying oven will remain at a constant temperature.
6. When using the drying box, set the time. After the time is up, what is the working condition of the drying box?
A: After the time is up, the drying oven will stop working.
Shanghai Brocent as Wuhan brainstorming Equipment Co. friendly brands manufacturers, which use high-performance drying oven CPU processing chip and high sensitivity, precision platinum resistance sensor temperature control system, the temperature control is more precise, more convenient operation .

Natural Plant Extract is a kind of solid powder obtained by cleaning, extracting, concentrating and spray drying Chinese herbal fruits and vegetables, without adding any other ingredients; The effective components and essence of plants are extracted, which improves the full utilization rate of plants and is beneficial to human absorption.
The components of plant extracts can be divided into glycosides, acids, polyphenols, polysaccharides, terpenoids, flavonoids, alkaloids and so on. For example, the main component of green tea extract is tea polyphenols. Ginseng extract mainly contains a variety of ginseng monomer saponins; According to different characters, it can be divided into extract, powder, lens, etc., such as violet leaf extract, hang white chrysanthemum extract.
