Description

Technical Field

[0001] The utility model belongs to spiral concentrating equipment, in particular to a material blocking structure of the spiral concentrating equipment. Background Art

[0002] After the low-temperature soybean meal is leached (extracted) with a 70% ethanol aqueous solution, a soybean concentrated protein with a protein content (dry basis) of 65-70% can be obtained. The anti-nutrients (such as trypsin, flatulence factor, etc.) and sugars in it are greatly reduced. It has the advantages of good palatability, no beany smell, and high digestion and absorption rate. It can be made into a variety of functional proteins after modification, and has good oil and water retention and dispersibility. It can be widely used in bread, ham, convenience food and other fields. It can also be used in animal milk replacers (such as dairy cows, beef cattle, etc.), and replace scarce proteins such as fish meal in feed.

[0003] However, although food-grade soybean protein concentrate has high economic value, there are great technical difficulties in its production process: desolventization and drying. In order to reduce the drying time, the wet soybean meal after alcohol soaking is generally first physically squeezed and concentrated by a spiral concentrator, and then the squeezed and concentrated wet meal is discharged into a normal pressure horizontal disc dryer for pre-desolventization, and most of the ethanol is evaporated in this process; finally, the desolventized wet meal is lifted into a vertical disc dryer, which also uses indirect normal pressure heating to evaporate the residual ethanol and most of the water.

[0004] However, since the existing spiral concentrating equipment has a relatively simple structure and cannot flexibly adjust the distance between the spiral body in the spiral concentrating equipment and the shell side wall or the material blocking plate during the concentration process of soybean wet meal, the spiral concentrating equipment has a limited extrusion effect and a fixed compression ratio, and cannot significantly reduce the liquid content in the soybean wet meal. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a material blocking structure of a spiral concentrating device which can flexibly adjust the compression ratio of the spiral during the concentration process of solid materials such as soybean wet meal, thereby increasing the discharge difficulty of the material at the tail of the spiral, improving the extrusion effect of the spiral, and further reducing the liquid content in the material.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: a material blocking structure of a spiral concentrating device, which includes a material blocking baffle plate arranged between the solid material discharge port of the spiral concentrating device and the discharge end of the spiral of the spiral concentrating device, the material blocking baffle plate and the discharge end of the spiral of the spiral concentrating device are arranged relative to each other, and a linear drive mechanism is transmission-connected to the side of the material blocking baffle plate away from the spiral, and the linear drive mechanism can drive the material blocking baffle plate to approach or away from the discharge end of the spiral. In this way, during the concentration and extrusion process of the material, the utility model can change the distance between the material blocking baffle plate and the discharge end of the spiral of the spiral concentrating device by controlling the linear drive mechanism, thereby changing the compression ratio of the spiral, so as to increase the discharge difficulty of the material at the tail of the spiral, improve the extrusion effect of the spiral, and further reduce the liquid content in the material.

[0007] Furthermore, the material blocking baffle is sleeved on the rotating shaft of the spiral body through a shaft sleeve, and the material blocking baffle can move along the axial direction of the rotating shaft of the spiral body to adjust the compression ratio of the spiral body.

[0008] Furthermore, the linear drive mechanism includes a hydraulic cylinder, the cylinder body of the hydraulic cylinder is installed on the equipment housing through an articulated seat, the end of the piston rod of the hydraulic cylinder is installed on the side of the material blocking baffle away from the spiral body through an articulated seat, and the material blocking baffle is driven close to or away from the discharge end of the spiral body through the telescopic action of the piston rod in the hydraulic cylinder.

[0009] Furthermore, a material breaking piece is provided on the side of the material blocking baffle plate facing the spiral body, and a material breaking protrusion is provided on the surface of the material breaking piece, and the material breaking protrusion is preferably in a pyramid shape. In this way, during the concentration and extrusion process of the material, the utility model can tear up the agglomerated material through the material breaking piece on the material blocking baffle plate, so as to facilitate the cooling of the material, and also facilitate the transportation of the material and the subsequent drying process.

[0010] Furthermore, the material breaking piece is detachably mounted on the surface of the material blocking baffle plate by means of fasteners, and the fasteners are preferably countersunk screws, so that operators can easily replace the worn material breaking piece.

[0011] Furthermore, a temperature sensor and a humidity sensor are provided below the material blocking baffle, and the temperature and humidity of the material at the discharge end of the spiral are monitored in real time by the temperature sensor and the humidity sensor, so as to adjust the position of the material blocking baffle in the material blocking structure of the spiral concentrating equipment. That is, when the temperature of the material rises to exceed the critical value as the liquid content in the material decreases, the distance between the material blocking baffle and the discharge end of the spiral can be increased to prevent the material temperature from rising too high.

[0012] Furthermore, the spiral body is a variable pitch spiral body, and the spiral pitch of the spiral blades gradually decreases from the feeding direction to the discharging direction, thereby effectively improving the material transmission efficiency and avoiding the material blockage phenomenon.

[0013] It can be seen from the above technical scheme that the utility model has the following advantages: First, during the concentration and extrusion process of the material, the utility model can change the distance between the material blocking baffle and the discharge end of the spiral of the spiral concentration equipment by controlling the linear drive mechanism, thereby changing the compression ratio of the spiral, so as to increase the discharge difficulty of the material at the tail of the spiral, improve the extrusion effect of the spiral, and further reduce the liquid content in the material; at the same time, when the temperature of the material increases to exceed the critical value as the liquid content in the material decreases, the utility model can also increase the distance between the material blocking baffle and the discharge end of the spiral to prevent the material temperature from rising too high; secondly, during the concentration and extrusion process of the material, the utility model can also tear up the agglomerated material through the material breaking pieces on the material blocking baffle to facilitate the cooling of the material, and also facilitate the transportation of the material and the subsequent drying treatment.
