[0014] Beneficial Effects
[0015] Compared with the prior art, the advantages of the food testing dissolution device of the utility model are:
[0016] 1. The fixed crushing part and the rotating crushing part are used to crush the food together. Since the gap between the two is long and the gap gradually decreases from top to bottom, the time of acting on the food is long, the crushing process is gradual, and the crushing is more complete, which can ensure that the size of the food particles entering the dissolution chamber is basically the same.
[0017] 2. The first outer crushing wall is in the shape of a positive cone, and the third outer crushing wall is in the shape of an inverted cone, which is beneficial to further extend the time for food to be crushed in the gap and crush it more fully.
[0018] 3. The height of the rotating crushing part can be adjusted by the adjusting bolt of the height adjustment structure, thereby adjusting the gap size between the lower ends of the rotating crushing part and the fixed crushing part. Combined with the total time required for crushing and complete dissolution, the particle size most suitable for the food to be crushed at this time can be selected.
[0019] 4. The inner side of the fixed crushing part is flushed with water through the flushing port on the upper inner side wall of the fixed crushing part. Since the flushing direction of the flushing port is tangent to the inner side wall of the fixed crushing part, a swirl can be formed, which can flush the food particles remaining between the fixed crushing part and the rotating crushing part into the dissolving chamber, avoiding that the actual ratio of food to water in the dissolving chamber is significantly different from the predetermined ratio, thereby improving the accuracy of detection. In addition, the water flow is used to re-drop the food particles remaining in the crushing chamber, which is conducive to cleaning the crushing chamber.
[0020] 5. Introducing steam through the steam input pipe can disinfect the entire equipment to prevent the growth of bacteria from affecting subsequent test results.
[0021] 6. After the food particles enter the dissolution chamber, water is injected into the dissolution chamber through the water injection port, and then the mixture of water and food particles is stirred by the stirring mechanism. After the mixture is evenly mixed, the solution is discharged from the discharge port for detection. Since the food particles are relatively uniform in size, the dissolution efficiency is high, the food particles are well dissolved, and the accuracy during inspection is high. Since the stirring mechanism is provided with at least two rotating shafts, the spacing between adjacent rotating shafts is less than twice the length of the stirring rods, the stirring rods of adjacent rotating shafts are arranged alternately up and down, and the rotation directions of adjacent rotating shafts are opposite, then when each rotating shaft drives the stirring rods to stir, the stirring rods on the adjacent rotating shafts move towards each other, the liquid impact force at this location is large, turbulence is formed, the stirring is more sufficient, and the mixing effect of water and food particles is improved.
