Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a sample thawing device for food detection. Background Art

[0002] Food safety testing is the process of detecting harmful substances in food according to national standards, primarily focusing on harmful and toxic indicators such as heavy metals and aflatoxins. Food science and engineering is a crucial component in promoting the development of the food industry towards large-scale, continuous, and automated production.

[0003] Before food testing, some frozen foods need to be thawed. Currently, most frozen foods are thawed with warm water. After thawing, a large amount of water droplets will remain on the food to be tested. If it is taken out directly, the water droplets will drip everywhere, causing pollution to the surrounding environment and equipment, and affecting the actual use effect. Utility Model Content

[0004] The purpose of the present utility model is to provide a sample thawing device for food testing to solve the problems raised in the above background technology.

[0005] The top of the motor is connected with the gear train of claim 1, wherein the motor is connected to the gear train of the motor to the external gear of the motor, and the top of the motor is connected with the gear train of the motor to the external gear of the motor.

[0006] Preferably, a rectangular placement hole is provided on the outside of the placement tube, and a plurality of water inlet holes are provided on the outside of the placement tube.

[0007] Preferably, the gear ring is located below the lifting plate, and the gear ring is meshed with the gear.

[0008] Preferably, the transmission wheel 1 is located above the lifting plate, and the transmission wheel 1 is connected to the transmission wheel 2 through a transmission belt.

[0009] Preferably, the bottom end of the rotating shaft extends to the interior of the placement cylinder and is fixedly connected to the fan blades, and the fan blades are evenly distributed in a circular array around the center of the rotating shaft.

[0010] Preferably, the bottom end of the worm extends to the bottom of the box and is fixedly connected to the handwheel, and the worm is meshed with the outer side of the worm wheel.

[0011] Preferably, the number of the connecting shafts is four, and the connecting shafts are evenly distributed around the worm.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model is provided with a lifting plate, a placement cylinder, a gear ring, a gear and a fan blade. The placement cylinder is moved out of the liquid surface of the thawing box by an electric telescopic rod. Then, the motor drives the gear to rotate the placement cylinder and the food sample, so that the water droplets on the surface of the sample after thawing are thrown out by centrifugal force, thereby preventing the water droplets from dripping everywhere and affecting the subsequent detection of the food sample. When the motor drives the gear to rotate, it will drive the transmission wheel 1 to cooperate with the transmission belt to rotate the transmission wheel 2 and the rotating shaft, further driving the fan blade to rotate. The rotation of the fan blade generates wind that blows toward the sample surface, thereby improving the effect of removing water droplets on the sample surface.

[0014] 2. The present invention also provides a placement tube, a box body, a worm, a connecting shaft, a worm wheel and a splint. By rotating the worm, the worm wheel and the connecting shaft rotate synchronously, and the splint further moves in the limiting groove, thereby fixing the food sample inside the placement tube, preventing the sample from shifting or shaking when the placement tube rotates, and enhancing the water removal effect of the placement tube rotation by fixing the sample.

A limiting groove 17 is provided at the bottom of the placing cylinder 4, and the inside of the thawing box 1 is welded and fixed to the heating rod 18.

[0023] In order to facilitate the staff to place the sample into the placement tube 4, a rectangular placement hole is opened on the outside of the placement tube 4, and a plurality of water inlet holes are set on the outside of the placement tube 4, so that the thawing liquid in the thawing box 1 can enter the placement tube 4 through the water inlet holes.

[0024] In order to ensure uniform heating of the sample surface, the gear 7 drives the placement cylinder 4 and the gear ring 5 to rotate synchronously through the motor 6. The motor 6 drives the rotation of the placement cylinder 4, so that the sample is placed in the liquid surface of the thawing box 1. The placement cylinder 4 drives the sample to rotate synchronously, thereby enhancing the contact effect between the sample surface and the warm water and improving the thawing time of the sample.
