the vacuum tray dryer consists of a square or round vacuum chamber with customized fixed internal shelves; the wet material to be dried is loaded into pans or trays and manually placed on the shelves. The top part of each shelf is flat with a coil jacket on the underside to circulate steam or liquid heating medium for the desired operating temperature.
Due to hundreds of various products and demands of inducing and controlling a vacuum environment, almost all aspects of a vacuum tray dryer's mechanical design and ancillary support equipment can be customized to meet each process design need.

The required shelf surface area drives the overall dimension of each vacuum chamber of the vacuum tray dryer. The shelf size, spacing between each shelf, and selected chamber geometry (square or round) will determine the overall chamber size. by the way,the vacuum tray dryer also called vacuum shelf dryer.
Delicate, heat-sensitive materials are dried safely at drying temperatures. Operating under a vacuum, the product is protected from oxidation and atmospheric contamination, and released solvents are fully recovered.
vacuum tray dryers are specified for products requiring uniform, low-temperature drying with no agitation or compression. Among those products are pharmaceuticals, nutraceuticals, vitamin extracts, specialty food items, fine chemicals, and glandular products.
FZG Series lab model vacuum shelf dryer uses a vacuum pump to damp air out from the interior of the vacuum dryer machine and make the working chamber form vacuum status. and let the raw material be dried at vacuum condition, Therefore, the drying speed of raw material is improved and the energy is saved greatly. Because the raw materials load inside the tray (standard tray size:640x460x45mm, the tray of the vacuum tray dryers also can design as nonstandard machine), It is a static vacuum tray drying machine, and the form and structure of the material can't be damaged when dried. About the heating way of the vacuum dryer, it can use hot water, steam, or conduct oil. The exact heating way will be determined by the client workshop heat source situation. because the interior of the vacuum tray dryer machine is vacuum state. The temperature control is not accurate if testing the vacuum air temperature. So we have two ways to dissolve this issue. It can use a soft cable temperature sensor to test the material's temperature or the client adjust the heat source temperature. Notes: If the material contains a large number of solvents such as methanol, ethanol, etc. The solvent of raw material can be collected by using a condenser. But the condenser to recollected the solvent that needs the user to supply cooling water, If the solvent is water or low proportion of solvents, the condenser is not required in order to save investment cost.
Hywell machine also has the industrial vacuum shelf dryer. Hywell Machinery has the industrial vacuum tray dryers for the factory, please pay attention to hywell company's vacuum shelf dryer.
A laboratory vacuum tray dryer machine is a kind of vacuum drying equipment specially designed for laboratory or small-scale production. It is usually smaller, accommodates fewer samples, and is usually a sterile environment. A laboratory vacuum dryer usually consists of two main parts: a heating system and a vacuum chamber. The heating system is responsible for heating the sample to the set temperature; the vacuum chamber provides a vacuum environment to promote the evaporation of water.
Industrial vacuum dryers are usually used in large-scale industrial production. They can handle larger volumes of material and often do not require a sterile environment. Not only the large output but also the cost of the equipment need to be considered.

The vacuum tray dryer has a wide range of applications in various industries, including:
Vacuum tray dryers are widely used in the pharmaceutical industry for drying heat-sensitive drugs, herbal extracts, and other materials that require low-temperature drying.
In the food processing industry, vacuum tray dryers are used for drying fruits, vegetables, and other food products while retaining their nutritional value and flavor.
Vacuum tray dryers are extensively used in the chemical industry for drying organic compounds, pigments, and other sensitive materials that require low-temperature drying.
Vacuum tray dryers are used in the cosmetic industry for drying pigments, extracts, and other sensitive materials that require low-temperature drying.
Vacuum tray dryers also find applications in industries like ceramics, plastics, and minerals, among others.
Hywell Machinery are able to offer our FZG series Laboratory model vacuum tray dryer with contact part to be built in SS304, SS316L, Titanium, Duplex stainless steel, etc. Electrical parts of control system of the lab scale vacuum tray dryer can be adapted to the customer’s needs.
Pure water has the maximum vaporization rate when it is boiling. Under normal conditions, pure water starts to boil at about 100°C. Under vacuum conditions, because the partial pressure of water vapor in the system is much lower than the partial pressure of water vapor on the surface of the material, the boiling point of water is lower than 100°C. For example: when the surface drops to -0.07MPa, the water starts to boil at 70°C. So despite the lower operating temperature, the small scale vacuum tray dryer still has a larger drying capacity.
Hywell machinery FZG series vacuum tray dryer had the following advantages over conventional solutions.
Because all liquids vaporize at lower temperature at reduced pressures, it is possible to vaporize the liquids at very low temperatures.
Since the evaporation of the liquid under vacuum occurs at a much reduce temperature, the temperature differential is increased without raising the temperature.
Active pharmaceutical ingredients, drugs and toxic chemicals are easily isolated in a vacuum dryer. The closed system also assures the maximum collection of solvents is achieved, protecting operators and the environment.
Vacuum tray drying oven is ideal for avoiding oxidation of chemical and with the addition of an inert gas purge, an oxygen free environment can be maintained.
The materials load inside the tray of the vacuum shelf dryer ,So the shape of raw material to be dried should not be destroyed.
While selecting a vacuum tray dryer machine for your industrial drying process, consider the following factors:
The capacity of the vacuum shelf dryer should be chosen according to the quantity of material to be dried in a batch.
The material of construction should be chosen based on the properties of the material being dried and the process requirements. Stainless steel is the most commonly used material for construction.
For example, 316L stainless steel is generally selected for pharmaceutical materials, and polypropylene baking trays can be selected for corrosive materials; titanium baking trays can be selected for materials that cannot contact iron ions, such as the lithium battery industry.
The operating temperature of the vacuum tray dryer should be chosen based on the material being dried and the drying process requirements.
The vacuum level should be chosen based on the nature of the material being dried and the process requirements.
Automation features like programmable logic controllers (PLCs) and human-machine interfaces (HMIs) can enhance the efficiency and control of the drying process.
A: The main difference between a vacuum tray dryer and a conventional dryer is that a vacuum shelf drying machine operates under reduced pressure, which lowers the boiling point of the liquid to be removed, resulting in faster drying and preservation of the material being dried.
A: The advantages of using a conductive vacuum tray dryer include faster drying times, improved heat transfer rates, and reduced energy consumption.
A: Yes, a vacuum tray drying machine can be used for drying liquids by converting them into a powder or solid form.
A: The frequency of servicing a vacuum shelf dryer machine depends on various factors like usage, the material being dried, and operating conditions. However, it is recommended to perform regular cleaning, lubrication, and inspection of the components to ensure optimal performance and reliability.
