Portable ice-temperature fresh-keeping barrel for fresh apple juice

Abstract

The invention discloses a portable ice-temperature fresh-keeping barrel for fresh apple juice. The portable ice-temperature fresh-keeping barrel comprises a barrel plug, a shell, a miniature refrigeration compressor air inlet valve, an air pipe, a high-efficiency phase-change cold storage agent, a neck pipe, inner containers, a miniature refrigeration compressor, miniature refrigeration compressor air outlet holes and a power source base. The inner containers are coaxially and tightly arranged in the shell at intervals. The space between the inner containers and the shell is filled with the high-efficiency phase-change cold storage agent, the upper portions of the inner containers are coaxially and tightly communicated with the neck pipe, the diameter of the neck pipe is smaller than the minimum diameter of the inner containers, and the barrel plug can be detachably and tightly arranged on the neck pipe. The high-efficiency phase-change cold storage agent of the fresh-keeping barrel can effectively reduce temperature fluctuation in the barrel, so that the environment of the inner barrel is at a lower temperature for a long time. Compared with traditional vacuumizing cold insulation, the high-efficiency phase-change cold storage agent can achieve a better fresh-keeping effect, and fresh apple juice in the barrel is not prone to deterioration.

Description

technical field [0001] The invention belongs to the technical field of food, in particular to a portable freshly squeezed apple juice ice-temperature fresh-keeping bucket. Background technique [0002] There are following problems in the freshly squeezed juice ice temperature fresh-keeping bucket in the prior art: [0003] 1. The existing fresh-squeezed apple juice preservation barrels are not filled with cold storage agent or the cold storage capacity of the filled cold storage agent is not high, and the adverse consequences will be: (1) The temperature fluctuation of apple fresh-squeezed juice in the fresh-keeping barrel is large; (2) Fresh-keeping The freshly squeezed apple juice in the barrel cannot be kept at a lower temperature for a long time; (3) The freshly squeezed apple juice in the fresh-keeping barrel is easy to deteriorate. [0004] 2. The existing fresh-keeping barrels have no refrigeration device, and usually require external refrigeration equipment to coord...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing fresh-squeezed apple juice preservation barrels are not filled with cold storage agent or the cold storage capacity of the filled cold storage agent is not high, and the adverse consequences will be: (1) The temperature fluctuation of apple fresh-squeezed juice in the fresh-keeping barrel is large; (2) Fresh-keeping The freshly squeezed apple juice in the barrel cannot be kept at a lower temperature for a long time; (3) The freshly squeezed apple juice in the fresh-keeping barrel is easy to deteriorate

[0004] 2. The existing fresh-keeping barrels have no refrigeration device, and usually require external refrigeration equipment to coordinate their work

The adverse consequences that will be produced are: (1) the low temperature environment cannot be maintained for a long time in the fresh-keeping bucket; (2) the use of external refrigeration equipment will increase power consumption; (3) it cannot be transported over long distances

[0005] 3. The existing fresh-keeping bucket is inconvenient to carry. The reasons for this problem are: (1) The volume of the fresh-keeping bucket is too large; (2) During the carrying process of the fresh-keeping bucket, the temperature inside the bucket cannot be kept at a low temperature for a long time; (3) It cannot be refrigerated in time during the carrying process, and the low temperature environment in the barrel can be maintained

[0008] Disadvantages: ① No cold storage agent is used, and the purpose of fresh-keeping is only achieved by isolating the outside air, which can only reduce the probability of contamination of freshly squeezed apple juice, and cannot achieve the expected fresh-keeping effect; ② There is no independent refrigeration device, and it cannot be quickly refrigerated

[0010] Disadvantages: ① only by adjusting the displacement valve to obtain weak vacuum cooling, the cooling effect is weak, and the energy consumption is large; ② the insulation layer does not use high-efficiency phase change cold storage agent, the temperature fluctuates greatly, and the freshness preservation effect is poor

[0012] Disadvantages: ① No independent refrigeration equipment, unable to maintain low temperature environment in the barrel for a long time; ② Large volume, not easy to carry and transport; ③ Only rely on vacuum interlayer to keep cold, the effect is poor
