Abstract

The present invention relates to finely procession field of bamboo wood, and particularly to a technique for processing low-temperature retorting extracted liquid of bamboo. The technique comprises the following steps: (1) selecting fresh and clean bamboo wood for executing artificial impurity removing and eliminating stone block, crushed mud, etc.; (2) placing the bamboo wood into a gas retort for executing heating and temperature rising in normal pressure state, and keeping the temperature for 3 hours when the temperature obtains 88 DEG C to 92 DEG C for sufficiently eliminating water in the bamboo wood; and (3) slowly elevating temperature after heat keeping, collecting the extracted liquid of bamboo when the temperature obtains 96 DEG C to 100 DEG C until the time when the temperature obtains 116 DEG C to 120 DEG C. The liquid state extracted liquid of bamboo is obtained through cooling the gas-phase extracted liquid of bamboo. In the cooling process, the time when the temperature is elevated from 96-100 DEG C to 103-107 DEG C is controlled in 5 hours, and the time when the temperature is elevated from 103-107 DEG C to 116-120 DEG C is controlled in 3 hours. The low-temperature retorting extracted bamboo liquid production technique has the advantages of high yield, stable quality and high production efficiency.

Description

Technique for producing bamboo low-temperature dry distillation extract

Technical field

The present invention relates to bamboo deep processing field, relate in particular to a kind of technique for producing bamboo low-temperature dry distillation extract.

Background technology

Contain multiple organic principle in the bamboo, include the quasi-SOD natural activity factor, the bamboo extract is a kind of natural sterilization pest repellant, also has fresh-keeping, antioxidation, has bigger exploitation in fields such as agricultural, medical and health, health foods and is worth.At present, domestic bamboo extract mainly extracts firing in the bamboo charcoal process with earth kiln, obtains as the accessory substance of producing bamboo charcoal always, and the yield of product is low, quality is unstable.Chinese patent ZL3141584.9 discloses a kind of technology and equipment thereof of producing bamboo vinegar liquid, adopt dry distillation carbonizing furnace to produce bamboo charcoal and bamboo vinegar liquid, making significant headway aspect the control of the production technology of bamboo extract and quality stability, but, this technology is still more coarse, the bamboo vinegar liquid composition more complicated of producing, particularly invalid composition is more, influenced the developing of bamboo extract application, how to come the bamboo extract of production specific use at the meticulousr production technology of special application research and design is the realistic problem of being badly in need of solution in the bamboo deep processing field.

Summary of the invention

The object of the present invention is to provide a kind of production technology of bamboo low temperature extract of suitable suitability for industrialized production, require to have yield height, stay in grade, advantage of high production efficiency.

Technique for producing bamboo low-temperature dry distillation extract step of the present invention is as follows:

(1), select fresh clean bamboo wood, carry out artificial removal of impurities, reject stone, broken mud etc.;

(2), bamboo wood put into gas retort under atmospheric pressure state, carry out heat temperature raising, insulation is 3 hours when temperature reaches 88 ℃～92 ℃, allows bamboo wood fully dewater;

(3), continue slowly to heat up in the insulation back, when reaching 96 ℃～100 ℃, temperature begins to collect the bamboo extract of gas phase, reach 116 ℃～120 ℃ up to temperature, the bamboo extract of gas phase cools off by condenser, obtain liquid bamboo extract, in this process, temperature from the control of time of 96 ℃～100 ℃ to 103 ℃～107 ℃ at 5 hours, temperature from 103 ℃～107 ℃ to 116 ℃～120 ℃ time control at 3 hours.

Technique for producing bamboo low-temperature dry distillation extract of the present invention, selecting 96 ℃ to 120 ℃ intervals to carry out destructive distillation extracts, allow water vapour volatilize fully, improved the concentration of extract, in the active ingredient of fully extracting in the bamboo, because temperature is lower, has reduced the destruction to some active ingredient, also shortened the time of extracting simultaneously, improved production efficiency, and because temperature control is more accurate, the extract stable components that obtains has improved the quality of product, therefore, the present invention has also provides a kind of equipment of producing bamboo vinegar liquid, the bamboo vinegar in can more effective extraction bamboo, yield height of the present invention, stay in grade, advantage of high production efficiency.
