CN101057667A - Method for low temperature forced extracting bamboo juice - Google Patents

Abstract

The invention discloses a method for extracting bamboo juice at low temperature, comprising slice treatment, squeezing and separating, filtering, and freezing. The bamboo is cut into slice before squeezing, so the needed power for squeezing is small and it will not cause high temperature, which is helpful to keep effective component and original taste of bamboo juice. The invention is characterized by high product quality, short processing time, high juice concentration, low production cost, no smoke emission and wastewater and waste slag discharge.

Description

The method of low temperature forced extracting bamboo juice

(1) technical field: the present invention relates to a kind of extracting method of bamboo juice, particularly the low temperature of bamboo juice extracts.

(2) background technology: the medical care effect of bamboo juice is familiar with by China people already, at China's tool with long edible and medicinal history.Bamboo juice is mainly used in manufacturing medicine---bamboo juice now.Why is bamboo juice widely used in beverage, health products, field of food? mainly be because the extraction process of bamboo juice and the restriction of equipment.What adopted in the bamboo juice pharmaceutical factory now is that cooking process technology is extracted bamboo juice, be about to bamboo and remove branch, clean up, the bamboo piece is cut in fragmentation, enters pressure vessel, adds behind the water airtight, behind boiling certain hour under the certain temperature and pressure condition, it is soluble in water that bamboo juice leaches, again with the bamboo piece in the container and bamboo juice moisture from, obtain containing certain density bamboo juice water.The bamboo juice recovery rate of cooking process technology is very low, and is big to the bamboo wastage of material; And bamboo juice is water-soluble when leaching, and has further reduced concentration; High temperature during production can destroy some active ingredients in the bamboo juice, and health-care effect and drug effect are reduced.Chinese patent 200610033677 discloses a kind of extracting method of bamboo juice, it is to press extracting juice filtration sterilization and get product with former bamboo, though this method can be extracted bamboo juice preferably, but the squeezing of former bamboo is big and hard required power is big because of this health of bamboo, the temperature that is produced is still high, thereby big to the quality influence of bamboo juice; And place capacity is limited and can't satisfy society need.

(3) summary of the invention:

1, goal of the invention: the objective of the invention is to: a kind of bamboo juice recovery rate height is provided, saves bamboo resource, bamboo juice concentration height, health care and the strong low temperature forced extracting bamboo juice production technology of drug action.

2, technical scheme technical scheme of the present invention is:

A kind of method of low temperature forced extracting bamboo juice in turn includes the following steps:

A, raw material slicing treatment: select the cizu of growth in 1 to 3 year to make raw material, remove branch, clean up, be cut into the bamboo piece with bamboo cutter;

B, extruding separate: the bright bamboo piece that will cut is sent into the extruding seperator and is squeezed out juice, and the compression ratio that makes its extrusion spiral is greater than 4;

C, filtration: the bamboo juice that squeezes out enters filter press and filters the bamboo juice that obtains high concentration;

D, refrigeration: filtered bright bamboo juice refrigerated processing in 60 minutes.

3, beneficial effect: the present invention is owing to cut into slices former bamboo before squeezing, and required drive is little during squeezing, can not produce high temperature, can keep the active ingredient and the genuineness of bamboo juice, good product quality; The production efficiency height, the process time is short; Bamboo juice concentration height; Production cost is low; The protection environment, no flue dust discharging, without sewage discharge, no waste sludge discharge.Can reach goal of the invention fully.

(4) specific embodiment:

1), select the cizu of growth in 1 to 3 year, remove branch, clean up, be cut into the bamboo piece of 1.5 to 3 centimeter length with commercially available bamboo cutter.

2), bright bamboo piece is sent into extruding seperator (the extruding seperator is shown in Chinese patent 01257041.9).

3), the extruding seperator promptly begins to discharge bamboo juice and bamboo fibre by discharging opening respectively in 30 seconds.

4), the bamboo juice discharging opening bamboo juice of discharging sends in the commercially available filter press and filters, bamboo fibre is sent into the stacking of barnyard ground.

5), the bamboo juice that filters out contains a large amount of amino acid, trace element and sugar, bright bamboo juice is apt to deteriorate, for avoiding rotten, must send into as early as possible and freeze storehouse refrigeration.

Claims (1)

1, a kind of method of low temperature forced extracting bamboo juice in turn includes the following steps:

A, raw material slicing treatment: select the cizu of growth in 1 to 3 year to make raw material, remove branch, clean up, be cut into the bamboo piece with bamboo cutter;

B, extruding separate: the bright bamboo piece that will cut is sent into the extruding seperator and is squeezed out juice, and the compression ratio that makes its extrusion spiral is greater than 4;

C, filtration: the bamboo juice that squeezes out enters filter press and filters the bamboo juice that obtains high concentration;

D, refrigeration: filtered bright bamboo juice refrigerated processing in 60 minutes.
