Vacuum Shelf Dryers Consist 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 types of products and demands of inducing and controlling a vacuum environment, almost all aspects of a vacuum shelf dryer's mechanical design and ancillary support equipment can be customized to meet each individual process design needs.
The overall dimension of each vacuum chamber is driven by the required shelf surface area for drying. The shelf size, spacing between each shelf, and selected chamber geometry (square or round) will determine the overall chamber size.
Delicate, heat-sensitive materials are dried safely at extremely low drying temperatures. Operating under a vacuum, the product is protected from oxidation and atmospheric contamination, and released solvents are fully recovered.
Vacuum Shelf 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.
Hywell machinery company is a professional Vacuum Shelf Dryer Manufacturer that has two types of disc vacuum dryers; one is a square tray type vacuum dryer and the other is a circular vacuum dryer. The round shape vacuum dryer cannot load too many trays, so it is more suitable for drying less material per batch. Specific using circular shape vacuum dryers or square shape vacuum dryers, Hywell machinery's engineer will give recommendations according to material characteristics and single batch capacity.
If you need to dry liquids with high sugar content, such as honey, Chinese medicine extracts, etc., you can consider our company's high-efficiency vacuum dryer, the drying speed is 3-5 times faster than ordinary disc vacuum dryers.
A vacuum shelf dryer is a type of vacuum drying equipment that uses vacuum and low temperatures to dry heat-sensitive materials. This drying equipment consists of a vacuum chamber with several shelves, where the materials are placed for drying. The shelves are heated, and a vacuum is applied to remove the moisture from the materials.
The vacuum shelf dryer works by applying a vacuum and low temperatures to the materials to be dried. The materials are placed on the shelves inside the vacuum chamber. The shelves are heated, and a vacuum is applied to remove the moisture from the materials. The vacuum removes the moisture by lowering the boiling point of water, causing it to evaporate at lower temperatures.
Vacuum shelf dryers use low temperatures and high vacuum, which speeds up the drying process.
Vacuum shelf dryers ensure that the materials are dried evenly and free from any impurities, resulting in better product quality.
Vacuum shelf dryers are cost-effective because they consume less energy than other drying methods.
Vacuum shelf dryers can be used to dry a wide range of materials, including heat-sensitive products.
Vacuum shelf dryers can be expensive to purchase.
Vacuum shelf dryers require regular maintenance to ensure that they operate efficiently.
Vacuum shelf dryers have limited capacity, which can be a disadvantage for larger industries.
Vacuum shelf dryers are used in various industries, including:
• Pharmaceutical industry: Vacuum shelf dryers are used to dry pharmaceutical products like tablets, capsules, and powders.
• Food industry: Vacuum shelf dryers are used to dry food products like fruits, vegetables, and meat.
• Chemical industry: Vacuum shelf dryers are used to dry chemicals like pigments, dyes, and polymers.
To ensure that your vacuum shelf dryer operates continuously and efficiently, it is important to perform regular maintenance. Here are some maintenance tips for vacuum shelf dryers:
• Clean the vacuum chamber regularly to prevent any buildup of dust or other materials.
• Inspect the shelves for any damage or warping. Replace any damaged shelves immediately.
• Check the seals and gaskets for any wear or damage. Replace any damaged seals or gaskets immediately.
• Lubricate any moving parts to prevent wear and tear.
• Regularly check the vacuum pump for any signs of wear or damage.
By following these maintenance tips, you can ensure that your vacuum shelf dryer operates efficiently and lasts longer.
