Embodiment 1

[0038] After collecting bamboo that has grown for 3-5 years or unpolluted bamboo processing residues, use a disc-type bamboo crusher (for extrusion, cutting) to slice it, and the size of the bamboo slices is 4-6cm×4-6cm , and then placed in the bamboo and wood vinegar extraction and purification equipment of Korea Juyu Wood Vinegar Industry (2005-10 type), the temperature is controlled in the range of 200°C-500°C, and the self-ignition continuous dry distillation is carried out, and the primary and secondary condensation are carried out. The temperature is controlled in the range of 80°C-120°C to obtain bamboo vinegar liquid and the temperature is controlled in the range of 100°C-120°C to obtain bamboo vinegar liquid, and the primary and secondary condensate are mixed in the mixing tank under normal temperature and pressure. Standing and purifying for 180 days in a natural state, the refined bamboo vinegar liquid can be obtained.

Abstract

The invention relates to a method for preparing food-grade bamboo vinegar by taking bamboo wood as a raw material, which is characterized by comprising the following steps of: a, preparing refined bamboo vinegar, namely crushing the bamboo wood into bamboo chips, performing dry distillation and carbonization on the bamboo chips, performing two-stage condensation, mixing the bamboo vinegar obtained by the two-stage condensation in a mixing tank, and standing and purifying; and b, preparing the food-grade bamboo vinegar, namely performing three-stage distillation and condensation on the refined bamboo vinegar obtained in the step a, and collecting condensate obtained by the third stage distillation and condensation in a storage tank so as to prepare the food-grade bamboo vinegar which is pure, colorless and free from smoke odor. The invention also relates to the food-grade bamboo vinegar, which is pure, colorless and free from the smoke odor, prepared by the method, and application of the food-grade bamboo vinegar in food and health care products.

Description

technical field [0001] The invention relates to a method for preparing food-grade bamboo vinegar (it is liquid itself, so it is also called bamboo vinegar liquid) by using bamboo as a raw material and the food-grade bamboo vinegar. Background technique [0002] Wang Zhiyong's "Application of Bamboo Vinegar and Introduction to Its Industrialized Production" ("Forest Engineering" July 2008, Volume 24 No. 4) discloses that bamboo vinegar is a liquid extracted from the bamboo charring process, which has the functions of disinfection, It can deodorize, promote plant growth, improve soil, etc. It can be used as soil fungicide, plant growth promoter, odor remover, and can be used in the development of beauty and skin care products, and even in the treatment of diabetes. At present, this product is still produced by collecting the volatiles produced when burning bamboo charcoal in earthen kilns. It is used as a by-product of firing bamboo charcoal. Therefore, not only the output is ...
