Beef slice dryer with magnetic vibration function

Abstract

The invention discloses a beef slice dryer with a magnetic vibration function. A water tank is arranged in a heat-preservation enclosure. Water is injected into the water tank for submerging a spiral coil A and a spiral coil B in the water tank. A compressor A, the spiral coil A, a capillary tube A, an indoor unit of a refrigerating air conditioner and relevant pipelines form a heat pump circulating dehumidifying system set A. An outdoor unit of a heating air conditioner, an indoor unit of the heating air conditioner, a capillary tube B, the spiral coil B and relevant pipelines form a heat pump circulating heating system set B. The system A and the system B work alternately for achieving evaporation, condensation and discharging of moistures of beef slices in the heat-preservation enclosure and storage and utilization of heat in the water tank. The heat-preservation enclosure is further internally provided with a magnetism driven screen differential motion and impulse type vibration device and convection fans. Compared with an existing gas-state dehumidifying and drying method, the energy consumption is greatly lowered, and refrigerating and dehumidifying can be achieved with zero heat discharge; and screen vertical differential motion and impulse type vibration are alternately driven by magnetic force, beef slice stirring is particularly facilitated, hardening of the beef slices is prevented, and airflow can penetrate through the beef slices easily for drying the beef slices.

Description

technical field [0001] The invention relates to a beef slice drying device with magnetic vibration. Background technique [0002] The drying process of beef slices is essentially the process of draining the moisture in the beef slices. However, almost all of the existing drying equipment uses direct heating to discharge the moisture in the beef slices in the form of gaseous water, because the enthalpy of gaseous water is far away. It is much higher than liquid water and has a higher temperature. Therefore, a large amount of energy is also discharged when gaseous water is discharged, which inevitably causes a large amount of heat energy loss. This is obviously not in line with my country's current energy conservation and emission reduction policies. [0003] Secondly, most of the heating methods of existing drying equipment are direct heating, that is, direct heating by steam or electricity or heat transfer oil, but the thermal conversion efficiency of direct heating is low, a...

Problems solved by technology

[0002] The drying process of beef slices is essentially the process of draining the moisture in the beef slices. However, almost all of the existing drying equipment uses direct heating to discharge the moisture in the beef slices in the form of gaseous water, because the enthalpy of gaseous water is far away. It is much higher than liquid water and has a higher temperature, so gaseous water also discharges a large amount of energy, which inevitably causes a large amount of heat loss, which is obviously not in line with my country's current energy-saving and emission-reduction policies.

[0003] Secondly, most of the heating methods of existing drying equipment are direct heating, that is, direct heating by steam or electricity or heat transfer oil, but the thermal conversion efficiency of direct heating is low, and the thermal conversion rate of large boilers can only reach 90% The energy efficiency of heat pump heat transfer is relatively high, which can reach more than 3, which greatly improves the efficiency of heat energy utilization and realizes energy saving and emission reduction.

[0004] Thirdly, if the beef slices are stacked closely together, it is easy to harden during the drying process, which will hinder the evaporation of water and reduce the drying efficiency
