Frozen NFC fruit juice pre-melting tunnel

Abstract

The invention relates to the field of fruit juice product unfreezing, in particular to a frozen NFC fruit juice pre-melting tunnel. The device comprises an enclosure structure, a pre-melting chamber, a fan chamber, a partition plate, a fan return air inlet, a feeding device, a discharging device, a feeding door and a discharging door. Fruit juice is fed into the pre-melting chamber through a feeding trolley on feeding equipment, and then a centrifugal fan in a fan chamber feeds hot air with the temperature not exceeding 90 DEG C into the pre-melting chamber along an air supply pipeline. Hot air exchanges heat with frozen juice, and the juice is melted with the edge of the juice barrel. And the hot air returns to the steam heat exchanger of the fan chamber from the air return pipeline for heat exchange, and then is circulated into the pre-melting chamber. And the fruit juice is conveyed along the tunnel roller conveyor and is finally carried away by the discharging equipment.

Description

technical field [0001] The patent of the invention relates to the field of thawing fruit juice products, specifically a frozen NFC fruit juice pre-thawing tunnel. Background technique [0002] Frozen NFC juice is currently the raw material of NFC juice drinks. The main fruit producing areas put the produced raw materials into about 200L metal barrels and quickly freeze them to -18°C. Chain logistics transport to NFC fruit juice beverage factory to ensure the quality of juice raw materials. In the factory, it is processed into bottled NFC juice drinks on the market through processes such as thawing, blending, and packaging. [0003] The current thawing method for frozen NFC juice is to place the juice bucket in a normal temperature environment to thaw naturally, but natural thawing in a normal temperature environment takes up a lot of space, has high environmental requirements, and is inflexible in scheduling. The most important thing is that a long thawing time will serious...
