Simple freeze dryer

Abstract

The invention relates to a simple freeze dryer which comprises a dryer body, a support plate, a door opening motor, a threaded rod, a nut, handles, connecting blocks, a door cover and a dryer body. The simple freeze dryer is characterized in that the support plate is arranged under the dryer door on one side of the dryer body, and the dryer door is convexly arranged on the dryer body; the door cover is arranged on the dryer door, and the connecting blocks are arranged on the two sides of the door cover; the door cover are respectively connected with the two handles through the connecting blocks on the two sides, and the handles penetrate through the upper end of the threaded rod and arranged on the threaded rod; the lower end of threaded rod penetrates through the support plate and is connected with the support plate through the nut on the support plate, and the nut is arranged on the support plate and can rotate on the support plate. The door opening motor drives the nut, therefore the threaded rod correspondingly screwed with the nut moves up and down, and the purpose of opening the door is achieved. When the door cover completely leaves the upper part of the dryer door, the door cover can be rotated through the handles, and therefore the inner part and the outer part of the door cover can be easily cleaned and disinfected.

Description

technical field [0001] The invention relates to the field of drying equipment, in particular to a simple freeze dryer. Background technique [0002] Drying equipment is also called dryer and dryer. The equipment used for drying operation, the moisture in the material (generally refers to water or other volatile liquid components) is vaporized and escaped by heating to obtain a solid material with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. For example, drying wood before making wooden molds and woodware can prevent product deformation, and drying ceramic blanks before calcination can prevent cracking of finished products. In addition, the dried materials are also convenient for transportation and storage, such as drying the harvested grains below a certain moisture content to prevent mildew. Since natural drying is far from meeting the needs of production development, various mechanized dryers are more an...

Problems solved by technology

[0004] Freeze dryers are currently widely used in the textile and papermaking industry. Since the drying box of the freeze dryer is isolated from the outside world, when it is necessary to take and place dry items, it is generally achieved through a buffer room and a corresponding closeable door. However, the current closeable door is due to The structure is complicated, and it is extremely inconvenient to clean and disinfect. At present, there is no simple freeze dryer with a wide range of applications, a simple structure, and convenient cleaning and disinfection operations.
