As shown in fig. 1, the preparation method of the pagodatree flower extract in the embodiment adopts the dry pagodatree flower with bud-shaped raw materials, the water content is 12%, and the preparation method comprises the following steps:
steaming: the dry pagodatree flower raw material is directly added into a steaming drawer of a steamer without operations such as cleaning, impurity removal, soaking and the like, covered and sealed, high-temperature steam is introduced into the steamer through a pipeline to be heated, the temperature is kept at 90 ℃, the pagodatree flower raw material is steamed for 15 minutes, the pagodatree flower is heated to be disinfected and sterilized, the water content of the pagodatree flower is increased to 17-20%, the water content of the pagodatree flower raw material is uniform, and the raw material loss in a crushing procedure is reduced.
Each steamer can steam the pagodatree flower by about 500kg each time, and each batch of the pagodatree flower is steamed for 4 times by using two steamers. The steam condensate water produced by steaming is recovered to a usable liquid recovery tank for boiling process water.
Crushing: and opening the steamer, and putting the pagodatree flower after high-temperature sterilization into a crusher for crushing to obtain pagodatree flower coarse powder. The dust generated by the crusher is collected by a bag-type dust collector and is also used as pagodatree flower coarse powder.
Boiling: adding the pagodatree flower coarse powder into a stirrer, and adding the pagodatree flower coarse powder into the stirrer according to the weight ratio through a pipeline: water = 1:2, adding the steam condensate recycled in the available liquid recovery tank, indirectly heating to about 90 ℃ by steam, boiling for 10-15 min, disinfecting and sterilizing the pagodatree flower again, and then standing and cooling.
The steam indirect heating process has about 15 percent of steam loss, and the rest steam forms steam condensate water after condensation and is recycled to the usable liquid recycling pool for reuse.
And (3) centrifuging: and (3) pumping the boiled material into a three-foot centrifugal dehydrator (2000 rpm) for centrifugal dehydration for about 5min. The centrifugal force generated by high-speed rotation is utilized by the tripodal centrifuge to carry out centrifugal sedimentation on the suspension liquid added into the rotary drum, granular solid phase matters are settled on the wall of the rotary drum, centrifugal wastewater is discharged through a drain pipe, feeding is stopped when the settled materials in the centrifuge reach a certain amount, a power supply is cut off, the rotary drum is stopped to operate by means of braking, and the dehydrated pagodatree flower coarse powder is taken out manually. The centrifugal wastewater is discharged into a sewage treatment station for treatment, and the main pollutants of the centrifugal wastewater are pH, COD, BOD, SS and the like.
Extracting: taking out flos Sophorae Immaturus coarse powder from centrifuge, transferring to extraction tank (volume 10 m) 3 ) And (3) inner part. Borax, slaked lime and water are firstly put in a closed dissolving tank (volume 2 m) according to the weight ratio of 1:1:250 3 ) Internal mixing, collecting supernatant as clarified lime water, pumping the clarified lime water into a liquid storage tank (volume 10 m) 3 ) And (5) temporarily storing, and pumping into an extraction tank during extraction. The pipeline is provided with a valve for controlling the flow speed and the flow quantity of the clarified lime water. The extraction is carried out at normal temperature for about 2-3 h, the pH is regulated to 7-8, the lower part of the extraction tank is connected to the crystallization pond through an extraction liquid pipeline, and the extraction liquid pipeline is provided with a valve, so that the extraction liquid can be controlled to flow out.
And (5) squeezing the extracted pagodatree flower residues to a squeezer for dehydration, and returning the squeezed water to an extraction tank for re-extraction. The dehydrated waste residues are put into a plastic barrel to be temporarily stored in a waste residue temporary storage room and are sold as fertilizer raw materials and feeds.
The clarified lime water is directly added into a closed dissolving tank (volume 2 m) filled with water and borax by the negative pressure of the slaked lime powder 3 ) And (3) internal mixing, wherein dust cannot escape in the batching process, and sediment at the bottom of the dissolving tank is cleaned periodically every week to perform general solid waste collection treatment.
And (3) crystallization: the 30% hydrochloric acid solution is stored in a hydrochloric acid storage tank, and pumped into a crystallization pond from the bottom by a hydrochloric acid conveying pipeline. The extracting solution pipeline is connected with the hydrochloric acid conveying pipeline, the hydrochloric acid conveying pipeline is provided with a valve, when extracting solution enters the crystallization pond (5 m multiplied by 1.5 m), the valve on the hydrochloric acid conveying pipeline is opened, 30% hydrochloric acid solution is pumped according to a set flow, and the extracting solution are mixed in the pipeline in advance, so that the mixing effect is better, and then the extracting solution enters the crystallization pond for crystallization. During the feeding period, the pH value of the solution is detected by test paper, the pH value is regulated to 4-4.5, and the solution is stood for crystallization for 3 hours at normal temperature. The purpose of regulating the pH value of the solution is to make the pagodatree flower extract in the solution be continuously crystallized and separated out by utilizing the principle that the solubility of organic matters at different pH values is different. About 39.2kg of 30% hydrochloric acid solution was required for each batch of 4t dry pagodatree flower crystals.
