Description

Technical Field

[0001] The invention relates to the technical field of desiccant preparation, in particular to a food desiccant mixing and drying integrated tank. Background Art

[0002] Food desiccant refers to a substance used to absorb moisture in items to prevent them from getting wet. Common food desiccants include calcium oxide desiccant, silica gel desiccant, montmorillonite desiccant, calcium chloride desiccant and fiber desiccant. Food desiccant is used to avoid the occurrence of defective products caused by excess moisture and to ensure long-term storage of food. Food desiccant is usually made by heating and dissolving the raw materials and then mixing them with other raw materials. The mixed raw materials are then dried and crystallized.

[0003] At present, the mixing and drying of food desiccant are carried out in steps using a mixer and a drying equipment respectively. This production method not only has high equipment cost but also requires a raw material transfer process between mixing and drying. The temperature of the raw materials discharged from the mixing is too high. In order to avoid burns, the raw materials need to be cooled down, resulting in a problem of too long transfer time, which prolongs the time required for food desiccant production. There is a lack of a mixing and drying integrated equipment. Moreover, both the mixing and drying processes require heating of the raw materials. The raw materials are dissolved by heat during mixing, and the water is evaporated by heat during drying.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The food desiccant mixing and drying integrated tank is provided with a mixing tank, a drying cylinder and stirring blades. When the raw materials are heated and dissolved in the mixing tank, the rotating motor drives the sub-gear to rotate, the sub-gear drives the main gear to rotate, the main gear drives the first fixed shaft to rotate, the first fixed shaft drives the drying cylinder to rotate, the drying cylinder drives the stirring blades in the mixing tank to stir and mix the raw materials, so as to promote rapid mixing of various raw materials.

By installing the drying cylinder inside the mixing tank, the step of transferring the raw materials between the equipment can be eliminated, and the mechanical energy of the drying cylinder drum drying can be used for mixing and stirring in the mixing tank at the same time, thereby reducing the equipment cost and accelerating the efficiency of food desiccant production.

[0019] 2. The food desiccant mixing and drying integrated tank is provided with a heat transfer mechanism. During the mixing process of the raw materials in the mixing tank, the heating equipment converts electrical energy into thermal energy and discharges it into the mixing tank. Part of the thermal energy in the mixing tank is pumped into the connecting pipe by the blower. The hot air enters the hot air inlet pipe from the connecting pipe and finally enters the drying cylinder. The raw materials are dried by the hot air to accelerate the evaporation of water and make the raw materials dry and crystallized. Part of the heat in the mixing heating process is reused for raw material drying, thereby increasing the thermal energy utilization rate, reducing the power consumption, and making the food desiccant production process more environmentally friendly.

[0020] 3. The food desiccant mixing and drying integrated tank is provided with a scraping mechanism. The raw materials mixed in the mixing tank are in a paste state and adhere to the inner wall of the mixing tank, the outer wall of the drying cylinder and the surface of the stirring blade.

The outer wall of the scraping ring scrapes the raw materials on the inner wall of the mixing tank, the inner wall of the scraping ring scrapes the raw materials on the outer wall of the drying cylinder, and the inner wall of the through groove scrapes the raw materials on the surface of the stirring blade. The paste raw materials are pushed from the mixing tank into the conical groove and enter the drying cylinder from the inlet and outlet of the conical groove for drying. The scraping ring can greatly reduce the residual raw materials in the mixing tank when transferring the raw material process, which not only reduces the trouble of cleaning the subsequent mixing tank but also saves raw material resources.

[0021] 4. The food desiccant mixing and drying integrated tank is provided with a conical groove and a blocking mechanism. When the raw materials are transferred to the drying cylinder and discharged from the drying cylinder, the rotating shaft is driven to rotate by the turning motor, and the rotating shaft drives the mixing tank to turn relative to the bracket.

The paste raw materials are gradually pressed into the conical groove 15, and the paste raw materials flow into the drying cylinder 9 through the inlet and outlet 151 along the inner wall of the conical groove 15. The scraper ring 171 is driven downward by the reverse rotation of the scraper motor 193, so that the scraper ring 171 reciprocates up and down, pushing the remaining raw materials into the drying cylinder 9, and then the rotating cylinder 162 is turned over and reset, driving the baffle 1532 to extend from the movable groove 152 to block the inlet and outlet 151, and the telescopic cylinder 163 is contracted to pull the insertion rod 164 out of the slot 1533, and then the turning motor 8 is rotated and reset, driving the mixing tank 1 to rotate to a horizontal state, and the rotating motor 22 drives the sub-gear 21 to rotate.The secondary gear 21 drives the main gear 20 to rotate, the main gear 20 drives the first fixed shaft 11 to rotate, the first fixed shaft 11 drives the drying cylinder 9 to rotate, and at the same time, the blower 141 draws part of the heat energy in the mixing tank 1 into the connecting pipe 142, and the hot air enters the hot air inlet pipe 143 from the connecting pipe 142, and finally enters the drying cylinder 9, and the hot air dries the raw materials to accelerate the evaporation of water, so that the raw materials are dried and crystallized. The rotation of the drying cylinder 9 drives the raw materials entering the drying stage inside to roll, so that the raw materials are evenly dried. After drying, the turning motor 8 repeats the above operation to drive the mixing tank 1 to turn over, so that the conical groove 15 on one side of the drying cylinder 9 tilts downward by 30°, and then the driving mechanism 16 drives the blocking mechanism 153 to rotate, so that the inlet and outlet 151 is opened. At this time, the crystallized desiccant in the drying cylinder 9 slides down along the inner wall of the drying cylinder 9 and is discharged from the inlet and outlet 151. Finally, the material can be collected from the tank door.
