Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a pre-air drying device for a refrigerator. Background Art

[0002] A freezer is a mechanical device that uses a compressor to change the pressure change of the refrigerant gas to achieve low-temperature refrigeration. It is widely used in the field of food processing to keep food fresh through quick freezing. Most foods contain moisture, and the food itself is often cleaned before quick freezing to ensure the cleanliness of the food. This greatly increases the water content of the food, and adhesion will occur during quick freezing. A pre-drying process is required before the quick freezing process. Existing dryers mostly place the food on a tray and blow air on it with a fan to lose moisture on the surface of the food. This method does not turn the pre-dried food over or the turning operation is more cumbersome. The moisture at the bottom of the food is not easy to dry, resulting in uneven drying. There are water stains on the surface of the food, which affects the subsequent quick freezing process. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 3 As shown, the utility model provides a pre-drying device for a refrigerator, including a box body 1, a support column 2 is fixed at the bottom of the box body 1, a plurality of fans 3 are installed on the top and sides of the box body 1, an annular conveying track 4 is fixed on the top of the box body 1, half of the annular conveying track 4 is fixed in the box body 1 and the other half is fixed on the side of the box body 1, a slider 5 is installed in the annular conveying track 4, a clamp 6 is fixed at the bottom of the slider 5, and a drain trough 7 is fixed at the bottom of the box body 1.

[0023] refer to Figure 1 , Figure 2 and Figure 3 The clamping jaw mounting seat 601 is fixed at the bottom of the slider 5, and a connecting shaft 602 is connected to the clamping jaw mounting seat 601 through a ball bearing. A gear 603 is fixedly sleeved on the outer side of the lower part of the connecting shaft 602, and an electric-controlled clamping jaw 604 is fixed to the bottom of the connecting shaft 602. A rack 401 is provided at the outer bottom of the part of the annular conveying track 4 located inside the box body 1, and the rack 401 and the gear 603 are arranged on the same horizontal plane and are coupled to each other.

[0024] By setting a rack 401 on one side of the inner part of the circular conveyor track 4, the rack 401 is coupled with the gear 603, and the slider 5 moves forward along the conveyor belt in the circular conveyor track 4, so that the clamp 6 moves forward accordingly, and the gear teeth of the gear 603 on the clamp 6 are coupled in the tooth grooves of the rack 401. As the clamp 6 moves forward, the gear 603 rotates, and the connecting shaft 602 connected to the gear 603 rotates accordingly, driving the electric-controlled clamp 604 below to rotate together, so that the pre-dried food on the electric-controlled clamp 604 rotates, so that the fan 3 can completely blow to the surface of the food, thereby enhancing the air-drying effect.

[0025] refer to Figure 1 , Figure 2The annular conveying track 4 is located at both ends of the feeding port and the discharging port of the box body 1, and a positioning switch A402 and a positioning switch B403 are fixed respectively. The positioning switch A402 and the positioning switch B403 are electrically connected to the electric control clamp 604.

[0026] By installing positioning switch A402 and positioning switch B403 at the feed inlet and the discharge outlet respectively, and placing food under the positioning switch A402 at the feed inlet, after the clamp 6 reaches the positioning switch A402, the positioning switch A402 sends a signal to control the electric-controlled clamp 604 to clamp the food, and transport it to the positioning switch B403 at the discharge outlet via the circular conveyor track 4, the positioning switch B403 sends a signal to control the electric-controlled clamp 604 to release the food, thereby completing automatic discharge and improving production efficiency.

[0027] How to use

[0028] The working principle and use process of the utility model are as follows: food is placed under the positioning switch A402 at the feed inlet. After the clamp 6 reaches the positioning switch A402, the positioning switch A402 sends a signal to control the electric-controlled clamp 604 to clamp the food (the electric-controlled clamp 604 is a publicly available mature technology, and the positioning switch A402 is used to send a start signal to the driver in the electric-controlled clamp 604 to complete the clamping action). The clamp 6 is installed on the slider 5, and the slider 5 is installed in the annular conveying track 4. As the conveyor belt in the annular conveying track 4 drives the slider 5 forward, the clamp 6 moves forward, and the gear teeth of the gear 603 on the clamp 6 are coupled. In the tooth groove of the rack 401, as the gear 603 moves forward along the rack 401, the gear 603 rotates, driving the electric-controlled clamp 604 below to rotate together, so that the pre-dried food on the electric-controlled clamp 604 rotates, so that the fan 3 can completely blow to the surface of the food, enhancing the air-drying effect; after the air-drying is completed, the clamp 6 reaches the discharge port positioning switch B403, and the positioning switch B403 sends a signal to control the electric-controlled clamp 604 to release the food (the function of the positioning switch A402 is to send a start signal to the driver in the electric-controlled clamp 604 to complete the opening action), and the food falls on the connecting plate 101 and is transferred into the quick-freezing machine for quick freezing.
