Description

Technical Field

[0001] This utility model relates to the field of fresh bamboo deep processing equipment manufacturing technology, and in particular to the specific structure of a bamboo sap powder preparation production line. Background Technology

[0002] As is well known, China is a major bamboo resource country. Fresh bamboo contains about 50% water, known as bamboo sap or bamboo juice. In the "Compendium of Materia Medica," Li Shizhen praised it as "divine water," possessing extremely high medicinal value. However, in traditional bamboo processing, bamboo sap is not effectively recycled and is discarded, wasting resources and seriously polluting the environment. In my patent 202311027967.4, I also touched upon a method for recycling bamboo sap. However, in production practice, I later discovered that bamboo sap contains a relatively high amount of sugars, amino acids, bamboo flavonoids, vitamins, and other organic components. When in liquid form, it is very easy to deteriorate, which is not conducive to preservation and storage. Adding preservatives would destroy its original medicinal value. Secondly, the dry matter content of bamboo sap is low, accounting for only about 6% after being concentrated into bamboo sap powder, resulting in low efficiency in logistics and transportation. Therefore, in order to address these pain points, it is essential to innovatively design a bamboo sap powder preparation production line that is simple in structure, easy to implement, energy-saving, environmentally friendly, and highly automated, so as to provide a practical technical solution for the scientific recycling and efficient utilization of fresh bamboo resources.
