[0002] Vacuum freeze dryer is suitable for high-end raw materials, Chinese herbal medicines, biological materials, wild vegetables, dehydrated vegetables, food, fruit, chemical materials and other materials. Vacuum freeze dryer is mainly composed of refrigeration system and vacuum system. Its working principle is: using the vacuum drying principle, the wet material is frozen to the eutectic point temperature, the water in the material becomes solid ice, and then in a higher vacuum environment, the material is directly sublimated into ice by heating. The material water vapor is then condensed through a water vapor condenser in the vacuum system to achieve the purpose of dehydrating and drying the material. After using the vacuum freeze dryer for a period of time, the impurities inside it need to be cleaned.

[0003] When taking out materials from some existing vacuum freeze dryers on the market, the materials are relatively brittle after being stored in the vacuum freeze dryer for a period of time. This results in the materials easily producing debris when the stored materials are taken out, which falls into the inside of the vacuum freeze dryer, and it is time-consuming to clean up the debris. To this end, we propose a cleaning structure for vacuum freeze dryers to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-5 The utility model is described in further detail.

[0033] Embodiment 1, refer to Figure 1-5 In order to solve the existing problem that the material is brittle as a whole after being stored in a vacuum freeze dryer for a period of time, which leads to the material easily generating debris when the stored material is taken out and falling into the vacuum freeze dryer, and then it is time-consuming to clean the debris of the material, the utility model discloses a cleaning structure for a vacuum freeze dryer.

[0034] It includes a chassis body 1, and the left and right sides of the chassis body 1 are provided with slide grooves 2. The inside of the slide groove 2 is slidably connected with a support plate 3. The support plate 3 is composed of two sliders 301 and a bracket 302. The side surfaces of the two sliders 301 are slidably connected with the side surfaces inside the two slide grooves 2 respectively. The left and right sides of the bracket 302 are fixedly connected with the opposite side of the two sliders 301 respectively. A fixing bar 303 is movably inserted on the upper side of the bracket 302. The support plate 3 can support and place freeze-dried materials.

[0035] The fixing bar 303 includes a C-shaped rod 304, which is movably inserted into the upper side of the bracket 302. The bottom of the cross bar of the C-shaped rod 304 is fixedly connected to two first compression springs 309, and the bottom end of the first compression spring 309 is fixedly connected to the top of the bracket 302. The bottom ends of the two vertical rods of the C-shaped rod 304 both pass through the lower side of the bracket 302, and the opposite sides of the two vertical rods of the C-shaped rod 304 are fixedly connected with L-shaped blocks 306. By driving the two L-shaped blocks 306 to move downward with the C-shaped rod 304, the fixation of the bracket 302 can be released, so that the bracket 302 can be moved forward and the freeze-dried material can be quickly taken out.

[0036] The side surface of the vertical block of the L-shaped block 306 is slidably connected to the inside of the slot 7, and the front sides of the two vertical bars of the C-shaped rod 304 are fixedly connected with a scraper strip 305. The vertical cross-section of the scraper strip 305 is triangular in shape, and the bottom end of the scraper strip 305 is slidably connected to the bottom of the inner wall of the chassis body 1. The bottom of the scraper strip 305 with a triangular vertical cross-section is relatively sharp, so impurities on the bottom surface of the inner wall of the chassis body 1 can be scraped off more cleanly.

[0037] The specific working principle is: when it is necessary to clean the debris of the material, first open the chassis body 1, then move the C-shaped rod 304 downward to squeeze the two first compression springs 309, and at the same time, the C-shaped rod 304 drives the two L-shaped blocks 306 to move downward, so that the vertical block of the L-shaped block 306 moves out from the inside of the slot 7, thereby releasing the fixation of the bracket 302, and driving the material on the top of it to be stretched forward and taken out through the bracket 302, and at the same time, the C-shaped rod 304 moves downward and drives the scraper bar 305 to move downward, so that the scraper bar 305 moves forward at the same time as the material moves forward, and the debris inside the chassis body 1 is scraped out by the scraper bar 305, so that it is more convenient to clean the debris of the material.

A fixing groove 8 is provided on the right side of the chassis body 1, and a T-shaped groove 601 is provided on the rear side of the vertical bar of the C-shaped fixing handle 6. The inside of the T-shaped groove 601 is slidably connected to the T-shaped strip 602, and the side of the vertical bar of the T-shaped strip 602 is fixedly connected to two second compression springs 603, one end of the second compression spring 603 is fixedly connected to the inside of the vertical groove of the T-shaped groove 601, and the rear side of the horizontal bar of the T-shaped strip 602 is fixedly connected to a card plate 604, and the card plate 604 can be driven to move to the right by moving the T-shaped strip 602, so that the card plate 604 is released from the fixation to the chassis body 1.

[0040] The card plate 604 is composed of a connecting plate 605 and an L-shaped plate 606. The front side of the connecting plate 605 is fixedly connected to the rear side of the horizontal bar of the T-shaped bar 602, the side of the vertical plate of the L-shaped plate 606 is fixedly connected to the rear side of the connecting plate 605, the side of the horizontal plate of the L-shaped plate 606 is slidably connected to the inside of the fixed groove 8, and the left side of the connecting plate 605 is rounded. When people squeeze the connecting plate 605 with their palms, the connecting plate 605 can drive the L-shaped plate 606 to move to the right, so that the horizontal plate of the L-shaped plate 606 moves out from the inside of the fixed groove 8, and then the chassis body 1 is quickly opened.

[0041] The specific working principle is: by moving the connecting plate 605 to the right, the T-shaped bar 602 is driven to move to the right, the second compression spring 603 is squeezed, and at the same time the connecting plate 605 drives the L-shaped plate 606 to move to the right, so that the horizontal plate of the L-shaped plate 606 moves out from the inside of the fixed groove 8, and then the sealing cover 5 is driven forward by the C-shaped baffle frame 308, so that the chassis body 1 can be quickly opened and the material on the upper side of the support plate 3 can be quickly taken out.

[0042] Example 3, refer to Figure 1-5 In order to solve the problem that the existing vacuum freeze dryer is relatively complicated to seal, in this embodiment, based on the same concept as the above-mentioned embodiment 1, the vacuum freeze dryer cleaning structure also includes:

[0044] A support base 101 is fixedly connected to the bottom of the chassis body 1, and the shape of the support base 101 is an isosceles trapezoid. The upper side of the front side of the chassis body 1 and the middle part of the front side of the chassis body 1 are movably connected with a silicone sealing strip 102, and the front side of the silicone sealing strip 102 is fixedly connected to the rear side of the sealing cover 5. The silicone sealing strip 102 increases the airtightness of the sealing cover 5 when fixing the chassis body 1. The isosceles trapezoidal support base 101 has a larger contact area with the ground than the chassis body 1, thereby improving the stability of the chassis body 1 placed on the ground.

[0045] The specific working principle is: by rotating the sealing cover 5 to the front side of the chassis body 1, the sealing cover 5 drives the two silicone sealing strips 102 to move to the front side of the chassis body 1, and then loosening the card plate 604, so that the card plate 604 drives the L-shaped plate 606 and the T-shaped strip 602 to move to the left through the rebound force of the second compression spring 603, and moves the horizontal plate of the L-shaped plate 606 to the inside of the fixed groove 8, thereby sealing the vacuum freeze dryer, and thus sealing the vacuum freeze dryer is more convenient.
