Description

Technical Field

[0001] This utility model relates to the technical field of natural extract production equipment, specifically a low-temperature pressure filtration device for natural extracts. Background Technology

[0002] Filter presses play a crucial role in the production of natural extracts, separating the residue from the extract.

[0003] In existing technologies, after the filter press discharges the filtrate, it is transported at room temperature through traditional pipelines. During room temperature transport, the sugars, proteins, and other nutrients in the extract are prone to becoming a culture medium for microorganisms, leading to spoilage or fermentation. Furthermore, in existing technologies, the filter cake is directly discharged at the bottom of the filter press, requiring manual cleaning later, which increases the labor intensity of the workers.

[0004] Therefore, we propose a low-temperature pressure filtration device for natural extracts. Utility Model Content

The filter cake conveying assembly includes a flat belt conveyor, a second support frame, and a baffle plate. The low-temperature conveying structure includes a water receiving tank, an aluminum plate, a temperature sensor, heat dissipation fins, a liquid outlet pipe, a mounting plate, a cooling fan, and a semiconductor cooling chip. The water receiving tank is fixedly installed on one side of the first support frame and is located below the drain pipe.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a low-temperature pressure filtration device for natural extracts, which has the following beneficial effects:

[0016] 1. This natural extract uses a low-temperature pressure filtration device with a low-temperature conveying structure. The low-temperature environment significantly reduces the growth rate of microorganisms such as bacteria and mold, preventing the extract from spoiling and deteriorating during transportation. The low temperature (2-8℃) can inhibit the reduction or decomposition of heat-sensitive components (such as enzymes and natural pigments), maintaining the biological activity and nutritional value of the extract.

[0017] 2. This low-temperature filter press for natural extracts allows the filter residue to fall onto the upper part of the filter cake conveying assembly after being discharged from the lower end of the filter press. The filter cake conveying assembly then transports the residue, improving the efficiency and convenience of the discharge process and reducing the labor intensity of the workers.
