Circulating fluidized bed equipment and pine pollen production method thereof

Abstract

The invention discloses circulation fluidized bed equipment and a pin pollen production method thereof. The equipment forms a circulating passage by a fan (1), a positive pressure circulating pipe (2), a function branch and a negative pressure circulating pipe (10) according to a communication sequence of an outlet of the fan (1), the positive pressure circulating pipe (2), the functional branch, the negative pressure circulating pipe (10) and the inlet of the fan (1), wherein the functional branch is used for separating or screening material and gas, the material is formed into a fluidized state in the action of the fan (1) and circularly flows in the circulating passage at high speed, and is subjected to drying, impurity removing, sterilizing, screening, crushing, mixing, concentrating, evaporating, distilling and other process operations in the circularly flowing process.

Description

technical field [0001] The invention relates to a circulating fluidized bed equipment suitable for drying, removing impurities, sterilizing, screening, crushing, mixing, concentrating, evaporating, distilling and other operations of granular materials, powder materials and liquid materials. Screening, ultrafine grinding, solid-gas separation, ultraviolet sterilization, evaporation, distillation and other fields. Background technique [0002] Invention patents ZL201010162887.6, ZL201010162941.7 and ZL201010162898.4 respectively disclose a kind of equipment for drying, screening and sterilizing powder materials. These three inventions are improved on the basis of boiling dryers. It is not reliable, but the concept of circulating fluidized bed is of great significance. The traditional circulating fluidized bed mostly refers to a kind of combustion technology of coal-fired boilers. The three invention patents expand the concept of circulating fluidized bed.

At present, the separation of impurities in pine pollen raw materials is mainly achieved by vibrating sieve screening. This method can only separate impurities in pine pollen that are larger than the particle size of pine pollen cells, and the screening efficiency is low.

Patents CN200310105344 and CN200320106449 disclose a method and equipment for drying and removing sand and impurities of pine pollen. The method and equipment are mainly used for separating heavy impurities, and the effect of separating light impurities larger than the particle size of pine pollen cells is not good. In addition, the equipment And method Because the time of the material in the equipment is only a few seconds, it is difficult to dry the pine pollen to the moisture content to meet the requirements of the pine pollen industry standard (GH / T1030-2004) through one drying operation

Pine pollen is mostly made into tablets for sale. From the drying of the flower spikes to obtain the pine pollen wool goods to pressing into tablets, it generally needs to be dried, screened, impurity removed, wall broken, mixed with auxiliary materials and liquid binders, and mixed. Drying, tableting, irradiation sterilization and other processes, drying and screening are raw material processing stages, which are completed by raw material manufacturers, impurity removal, wall breaking, mixing with auxiliary materials and liquid binders, mixture drying, and tableting are deep processing The first stage is completed by the deep processor, and the radiation sterilization is completed by a professional radiation sterilization processor. There are too many space-time conversions in production, which is prone to secondary pollution and high production costs.
