High-vacuum low-temperature whole kelp drying system based on MVR

Abstract

The invention provides a high-vacuum low-temperature whole kelp drying system based on MVR, and belongs to the technical field of modern ocean. The tank body, the upper sealing head and the lower sealing head form a fully-closed structure, through the reasonable layout of the clamping sleeve, the coil pipe and the hung kelp and the adoption of the axial flow fan to form a circulating air path, the drying efficiency is improved, the adverse effect of glue discharge and adhesion on the drying of the whole kelp is avoided, and the uniform heating of the whole kelp is realized. High-vacuum low-temperature kelp drying is achieved through the steam compressor, the problems that in the kelp drying process, glue is discharged, and the quality is affected by too high temperature are solved, nutritional ingredients in kelp are reserved as far as possible, the kelp drying process is not polluted by the outside world, meanwhile, waste heat of evaporated waste steam is recycled, and energy is saved. The problems of high energy consumption, low quality, low efficiency, dense personnel and the like are effectively solved. Meanwhile, the method can also be used for high-quality low-temperature drying processing of economic seaweeds such as asparagus and laver as well as prawns, fishes and the like.

Description

technical field [0001] The invention relates to a vacuum drying device, in particular to a high-efficiency energy-saving vacuum drying device that utilizes MVR technology for waste heat recovery and utilization, and high-vacuum-low-temperature drying of kelp. It belongs to the field of modern marine technology. Background technique [0002] Kelp is rich in a variety of nutrients that are beneficial to human health, and is an important part of the "marine granary" industrial chain; at the same time, kelp is also an important raw material in the "blue medicine warehouse" industrial chain. Quality, kelp polysaccharide and other components have high medicinal value. The processed kelp products mainly include salted kelp and light-dried kelp. The scalding in the existing salting process will produce a large amount of viscous sewage, the high temperature will cause the loss of nutrients, and the effective components in the kelp will be seriously damaged, so it cannot be used as ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a high-vacuum and low-temperature whole kelp drying system based on MVR, which adopts a fully-sealed tank structure, through a jacket, a coil, and a reasonable connection between the suspended kelp. layout, to achieve uniform heating of the entire kelp, improve heat transfer efficiency, and solve the problem of easy adhesion during the drying process of the entire kelp; use MVR technology to achieve high-vacuum and low-temperature kelp drying, avoiding glue and high temperature during the drying process of kelp If the temperature is too high, it will affect the quality and other problems. At the same time, the waste heat from the evaporated waste steam will be recycled to effectively solve the problems of high energy consumption, low quality, low efficiency, and dense personnel.
