Full-automatic vacuum low-temperature fruit and vegetable fast maturing device

Abstract

The invention discloses a full-automatic vacuum low-temperature fruit and vegetable fast maturing device which consists of three vacuum frying tanks, one oil storage tank, an oil pump, an oil pipe, a steam spraying device, a steam pipe, a vacuum pump, a vacuum pipe, a valve, a centrifugal motor, a working platform, a feeding manipulator and a programmable logic controller (PLC) programmable control system. The three vacuum frying tanks have the same structural performance, jointly use the same oil storage tank, and simultaneously run with different work steps. Each frying tank cover is provided with an automatic turning on/off mechanism, vegetable and fruit baskets are put into the frying tanks, and each frying tank cover is provided with an automatic locking/unlocking mechanism; the feeding manipulator can be used for automatically suspending the manually-filled vegetable and fruit baskets into the frying tanks and suspending the fried vegetable and fruit baskets out of the frying tanks. The vegetable and fruit are fried under the status of oxygen deficiency and low temperature, the color, the fragrance and the flavor are retained, and the effective components are retained, so that the fried fruit and vegetable are welcomed by consumers. The whole device is controlled by the PLC programmable control system, is full-automatic in working procedures such as oil charging, material charging, heating, vacuumizing, frying, centrifugally drying, timing, discharging and the like, and has the advantages of being high-efficiency, energy-saving, high-yield, stable in quality of the fired vegetable and fruit, and the like.

Description

technical field [0001] The invention relates to a food processing device, in particular to a fully automatic vacuum low-temperature quick-cooking device for fruits and vegetables. Background technique [0002] Fruits and vegetables are daily food that everyone needs. It is of great practical significance to provide a processed fruit and vegetable food with good color, aroma and taste while preserving effective nutrients. Applying the principle that the boiling point of oil liquid decreases in a vacuum environment, fry the fruit and vegetable slices in a vacuum frying tank. Since the boiling point of palm oil and other edible oils in a vacuum state is only 90°C to 92°C, it can be fried in a vacuum environment. The fruits and vegetables fried at low temperature meet the above requirements and are deeply welcomed by consumers. In addition, the frying oil is boiled at a low temperature, which avoids the problem of toxic substances produced by normal repeated frying and protects...

AI Technical Summary

Problems solved by technology

[0003] At present, there are domestic and imported vacuum fruit and vegetable frying machines in the domestic market. This type of vacuum frying machine includes a frying tank and an oil storage tank. Manual operation has low efficiency, low output, and high labor intensity.
