Description

Technical Field

[0001] The invention relates to the technical field of fresh bamboo deep processing and equipment manufacturing thereof, and in particular to a bamboo sap powder preparation method and the specific structure of its production line. Background Art

[0002] As we all know, China is a country with abundant bamboo resources. Fresh bamboo contains about 50% water, which is called bamboo sap or bamboo juice. In the Compendium of Materia Medica, it was praised by Li Shizhen as "magic water" and has extremely high medicinal value. However, in the traditional bamboo processing technology, bamboo sap has not been effectively recycled and discarded, which wastes resources and seriously pollutes the environment. In the patent 202311027967.4, I also involved the recycling method of bamboo sap, but later in production practice, I found that bamboo sap contains a variety of organic components such as rich sugars, amino acids, bamboo flavonoids and vitamins. It is very easy to deteriorate when it is in liquid state, which is not conducive to fresh-keeping and storage. If preservatives are added, its original ecological medicinal value will be destroyed; second, the dry matter content in bamboo sap is low, and it only accounts for about 6% after being concentrated into bamboo sap powder, and the logistics and transportation efficiency is not high. Therefore, in order to solve these pain points, it is very necessary for us to innovatively design a method for preparing bamboo sap powder, process bamboo sap water into solid bamboo sap powder that is easy to store and transport, and provide a flexible automated production line with simple structure, easy implementation, energy saving and environmental protection, and high degree of automation to realize this method, so as to provide a practical technical solution for the scientific recycling and efficient utilization of fresh bamboo resources. Summary of the invention

[0003] The purpose of the present invention is to avoid the shortcomings of the background technology and provide a method for preparing bamboo sap powder, that is, to use multiple single-function mechanical equipment to assemble into a flexible automated production line, to continuously process fresh bamboo to extract bamboo sap water, and then to dry and dehydrate the bamboo sap water to prepare bamboo sap powder.

[0004] Another object of the present invention is to provide a specific structure of a bamboo sap powder preparation production line with simple structure, easy implementation, energy saving and environmental protection, and high degree of automation for implementing the above-mentioned invention method.

[0005] The object of the present invention is achieved through the following technical scheme, a method for preparing bamboo sap powder, the main features and implementation steps of the invention are: One is to use a spraying method to rinse the fresh bamboo poles with clean water to remove the mud and dust carried by the bamboo poles.

[0006] The second method is to use mechanical crushing to flatten and crush fresh bamboo poles into bamboo filaments. The specific surface area of ​​the bamboo filaments after crushing is greatly increased, which is conducive to heat transfer during cooking and easy to dialyze bamboo juice from the bamboo filaments.

[0007] The third is to use a high temperature and high pressure cooking method to add clean water to the bamboo filament segments loaded into the No. 1 high pressure cooking pot at a mass ratio of 1:1→1.25 and perform the first cooking for 20→60 minutes.

[0008] Fourth, the solid-liquid separation method is used to separate the bamboo shreds that have been steamed for the first time. The separated bamboo sap enters the post-process, and the solid bamboo shreds are filled into the No. 2 high-pressure steaming pot.

[0009] Fifth, clean water is added to the bamboo residue in a mass ratio of 1:0.8→1.0 and a second steaming is performed for 20→60 minutes.

[0010] Sixth, the solid-liquid separation method is used to separate the bamboo residue after the second cooking. The separated bamboo water enters the subsequent process, and the solid bamboo residue is used as the raw material for the production of bamboo fiber.

[0011] Seventh, the bamboo sap water is removed and concentrated by integrated membrane separation and concentration, and then stored in a liquid storage tank for homogenization. The bamboo sap water obtained by solid-liquid separation has different concentrations, high impurity content, and unstable liquid temperature. It must be filtered and removed, integrated with membrane separation and concentration, and then stored in a liquid storage tank for homogenization pretreatment to provide qualified process conditions for subsequent construction.

[0012] Eighth, the bamboo sap water in the liquid storage tank is dehydrated by a spray drying method to prepare bamboo sap powder.

[0013] 9. Bamboo sap powder is canned according to different specifications.

[0014] The production process is as follows: spray fresh bamboo to remove mud and sand → crush it into bamboo silk segments → first high-pressure steaming → solid-liquid separation → second high-pressure steaming → solid-liquid separation → generate bamboo sap water and solid bamboo silk residue → bamboo sap water is stored for homogenization → dehydrated to produce bamboo sap powder → packaged and stored; the solid bamboo silk residue separated from the solid-liquid separation is used as a raw material for producing bamboo fiber.
