Method for extracting fresh bamboo juice by uniformly retorting bamboo chips

Abstract

The invention relates to a method for extracting fresh bamboo juice by uniformly dry-distilling bamboo chips, which comprises the following steps: firstly, taking fresh bamboos of which the surfaces are dried, sawing the bamboos into bamboo chips, putting the cleaned bamboo chips into a dry-distillation storage basket, putting the bamboo chips into a dry-distillation furnace body through a feeding door, and starting a heating device and a water vapor generator by a controller, the water vapor is quickly preheated under the action of the heating device to instantly reach a high temperature, so that water molecules in the bamboo chips or organic components in vascular bundles can be evaporated out in an extremely short time; when the temperature reaches the dry distillation temperature, the pressure stabilizing pump is started to provide air pressure for the dry distillation furnace body so as to maintain dynamic balance of the air pressure in the dry distillation furnace body, and the fan is started to provide air flow for the dry distillation furnace body, so that the bamboo chips are uniformly heated and subjected to dry distillation in the dry distillation furnace body, and when the humidity sensor detects that the humidity in the dry distillation furnace body reaches a threshold value, the fan is started; the controller closes the heating device, the steam generator, the stabilized pressure pump and the fan, then juice is collected and condensed, fresh bamboo juice is obtained, the yield is high, resource consumption is small, and the production cost is further reduced.

Description

technical field [0001] The invention relates to the technical field of extraction of fresh bamboo lees, in particular to a method for extracting fresh bamboo lees by uniform dry distillation of bamboo chips. Background technique [0002] Fresh bamboo leek is the liquid naturally drained from the fresh stalks of the gramineous plants Phyllostachys glauca McCluve, Phyllostachys nuda McClure and several plants of the same genus. Because it has the effect of clearing heat and reducing phlegm, it is used for lung It is an important ingredient in the treatment of lung-heat cough for cough with excessive phlegm, asthma and chest tightness, stroke with strong tongue, and convulsions caused by phlegm-heat in children. The traditional processing method has been recorded in ancient herbal medicines. There are two main methods. Method 1: "cut the bamboo to a length of two feet and open it up. Put two pieces of bricks against each other, set the bamboo on top, roast the drain with fire, ...

AI Technical Summary

Problems solved by technology

[0003] At present, the preparation and extraction methods of fresh bamboo leek are as follows: 1. fire roasting method, the waste of bamboo material is serious, the output is low, the yield rate is low, and the resource consumption is large. The extraction process is all carried out in an open environment, which has serious pollution to the environment and is difficult to monitor bamboo. The quality of leek; 2. Water boiling method, soak bamboo with water or alcoholic liquid, and then heat extraction, not only the extraction time is long, but also the content of active ingredients is low, easy to mold and deteriorate; 3. Dry distillation method, bamboo slices are placed in the furnace , the surface of the furnace body is equipped with a heating device, and the bottom of the furnace body is provided with a discharge port, and the bamboo slices are dry-distilled by the heating device to obtain fresh bamboo leek, which also has the problems of low output and large resource consumption
