AI Technical Summary

Problems solved by technology

However, for water shield with soft bottom, adopting the above-mentioned traditional blanching method will inevitably produce liquid, that is, the gelatin of water shield itself will be lost, and the quality of water shield will decline.
In addition, the above-mentioned traditional blanching and greening technology cannot adopt the international general quick-freezing and fresh-keeping technology, but can only add preservatives in its fresh-keeping technology.

Embodiment 1

[0007] Embodiment 1, enter the water shield with poor clarity into the air bubble cleaning machine, and carry out the automatic cleaning of the air bubble water flow, and the air bubble cleaning machine cleans for 10 minutes under the control of the stepless speed regulator; The drainage time is 10 minutes under the control of the governor, and the drainage rate is 60%. 1. Send it into the double-helix greening machine for greening. The tenderness of water shield is poor. The steam spray pressure is controlled by steam constant temperature electromagnetic cutting to 0.15mpa, and the temperature is 95°C. Water shield is heated at a uniform speed under the action of the screw propeller, and its heating time is 5 Minutes; 5. Enter the normal temperature water and ice water two-stage pre-cooling machine to pre-cool the gel, and the gel is firm and does not disperse.

Embodiment 2

[0008] Embodiment 2, the good water shield of cleanliness enters bubble cleaning machine, carries out bubble water flow automatic cleaning, and bubble cleaning machine cleans time 5 minutes under the control of stepless speed regulator; Drain under the control of the speed controller for 7 minutes, and the drainage rate is 60%; 3. Enter the screw feeder, and the screw feeder feeds under the control of the stepless speed controller, and the time for each batch of feeding is 10 seconds; 4. Send Put it into the double-helix greening machine for greening. The tenderness of water shield is good. The steam spray pressure is 0.15mpa controlled by steam constant temperature electromagnetic cutting, and the temperature is 95°C. Water shield is heated at a uniform speed under the action of the screw propeller, and its heating and killing time is 0.5 minutes; 1. Enter the room temperature water and ice water two-stage pre-cooling machine to pre-cool the gel, and the gel is firm and does n...

Abstract

A steam showering technique for steaming water shield to kill its active enzyme and prevent it from browning includes such steps as washing, dripdrying, and heating at 95 deg.C for 0.5-5 min in screwsteamer with steam nozzles.

Description

technical field [0001] The invention relates to a technology of steam spraying water shield to kill the active enzyme existing in the vegetable itself, so as to effectively prevent the water shield from browning during storage without producing liquid. It belongs to the technical field of greening vegetables. Background technique [0002] What the prior art adopted was that the vegetables were placed in hot water above 90°C for blanching. Blanching vegetables in hot water can kill the active enzymes present in the vegetables themselves, so as to prevent the vegetables from browning during storage. However, for the tender water shield, adopting the above-mentioned traditional blanching and finishing method will inevitably produce liquid, that is, the gelatin of water shield itself will be lost, and the quality of water shield will decline. Adopt the above-mentioned traditional blanching and greening technology in addition and just can't take the internationally general quic...
