Description

Dry fruit cleaning, drying technology
Technical field
The present invention relates to a kind of dry fruit cleaning, particularly dry fruit cleaning, drying technology.
Background technology
The Along with people's growth in the living standard, dry fruits such as raisins, dried apricot, red date are nutritious with it, storage endurance and receive the attention more than the People more and more.The post-production of dry fruit is cleaned, and is the key factor of decision dry fruit credit rating.Dry fruit is in the airing process; Accumulate all kinds of dirts in its superficial makings easily, flushing not thorough also can residual various dirts in the dry fruit superficial makings; If but washing time is oversize; Not only waste water, and cause dry fruit suction swelling phenomenon easily, increase the energy consumption and the intractability of follow-up baking operation.At present, it generally all is to adopt the heating, drying mode that the later stage oven dry of dry fruit after cleaning handled, and often causes the dry fruit dehydration too much, and mouthfeel hardening, dry and astringent influences the dried fruit product quality.
Summary of the invention
The object of the present invention is to provide a kind of dry fruit cleaning, drying technology; Its processing step is simple, can either fast and effeciently clean dry fruit, improves the dry fruit surface cleanliness; Can remove the moisture on dry fruit surface again fast; Improve the mouthfeel of dry fruit, eliminate the phenomenon of the dry fruit mouthfeel difference that causes because of heating, drying, improve product competitiveness.
The objective of the invention is to realize like this, a kind of dry fruit cleaning, drying technology comprises the following steps: successively
(1) raw material evenly is put on the mesh conveyer belt of circulation rotation at the stand, the mesh conveyer belt gets into purge chamber, dewatering station and drying chamber successively;
(2) purge chamber is by being divided into three parts after going to; Be respectively one-level washing storehouse, secondary washing storehouse and rinsing storehouse, arranging the high-pressure water pipe with nozzle in the upper and lower horizontal interval of mesh conveyer belt respectively in one-level washing storehouse and the secondary washing storehouse, the traffic direction of high-pressure water pipe and conveyer belt is perpendicular; Nozzle is all towards conveyer belt; Along the direction of advance of mesh conveyer belt, the hydraulic pressure in the high-pressure water pipe is by the root 25-30% that successively decreases, and its water temperature remains on 30 o-45 oBetween;
(3) the mesh conveyer belt upper and lower in the dewatering station is being provided with hair-dryer and air exhauster respectively, and the exhaust air rate of air exhauster is greater than the exhaust air rate of hair-dryer;
(4) dry the storehouse by being divided into continuous elementary oven dry storehouse and secondary after going in the drying chamber; The discharging port in secondary oven dry storehouse is being provided with the air blast of in the oven dry storehouse, blowing; The air outlet that is installed on feed end place, the elementary oven dry storehouse end face links to each other with said hair-dryer; Adverse current wind distances zone face height in the drying chamber generally between 10cm-20cm, wind speed 10 meter per seconds-16 meter per second;
(5) wind-warm syndrome that is blown in secondary oven dry storehouse from air blast is controlled at 30 o-45 oBetween.
As a kind of preferred version, the adverse current wind distances zone face height in the drying chamber generally between 12cm-15cm, wind speed 12 meter per seconds.
According to the surperficial dirt ash adhesion condition of dry fruit, the cleaning step that process using hydraulic pressure of the present invention successively decreases, the foreign material dirt that can either remove the dry fruit surface fast is husky, can reduce again and use water consumption; Then carry out the dehydration of not damaged negative pressure, the moisture dehydration rate on dry fruit surface can reach 90%.Dry fruit after the dehydration in the entering drying chamber, is being provided with the adverse current wind opposite with the conveyer belt transporting direction in the drying chamber under the conveying of conveyer belt, it is air-dry that dry fruit is carried out high speed; The moisture removal rate on dry fruit surface further reaches 99%, and also can keep suitable moisture in the dry fruit pulp, thereby guarantees that dry fruit is after a series of processed of process; Mouthfeel is neither too hard, nor too soft; The limpid health of appearance adopts the dry fruit after the PROCESS FOR TREATMENT of the present invention, and product competitiveness is greatly improved.Processing step of the present invention is simple; Can either be fast and effeciently raisins, dried apricot, red date, walnut, red dry fruit such as carry be cleaned; Improve the dry fruit surface cleanliness; Can remove the moisture on dry fruit surface again fast, improve the mouthfeel of dry fruit, eliminate the phenomenon of the dry fruit mouthfeel difference that causes because of heating, drying.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described in further detail.
Fig. 1 is a process chart of the present invention.
The specific embodiment
A kind of dry fruit cleaning, drying technology, as shown in Figure 1, comprise the following steps: successively
(1) raw material evenly is put on the mesh conveyer belt of circulation rotation at the stand, the mesh conveyer belt gets into purge chamber, dewatering station and drying chamber successively;
(2) purge chamber is respectively one-level washing storehouse, secondary washing storehouse and rinsing storehouse by being divided into three parts after going to, and is arranging the high-pressure water pipe with nozzle in the upper and lower horizontal interval of mesh conveyer belt respectively in one-level washing storehouse and the secondary washing storehouse; The traffic direction of high-pressure water pipe and conveyer belt is perpendicular, and nozzle is all towards conveyer belt, along the direction of advance of mesh conveyer belt; Hydraulic pressure in the high-pressure water pipe is by the root 25-30% that successively decreases, because the dry fruit that gets at first in the purge chamber is often the dirtiest, so need compare higher hydraulic pressure; Along with advancing of conveyer belt; Hydraulic pressure reduces step by step, can reduce the waste of water, can prevent the suction of dry fruit pulp again too much; Prevent that dry fruit pulp is damaged, the water temperature in the high-pressure water pipe remains on 30 o-45 oBetween, be preferably 30 oCommon spray header is housed in the rinsing storehouse.
(3) the mesh conveyer belt upper and lower in the dewatering station is being provided with hair-dryer and air exhauster respectively, and the exhaust air rate of air exhauster is greater than the exhaust air rate of hair-dryer; Airflow direction in the dewatering station moves from top to bottom, and dry fruit is carried out the dehydration of not damaged negative pressure.
(4) dry the storehouse by being divided into continuous elementary oven dry storehouse and secondary after going in the drying chamber; The discharging port in secondary oven dry storehouse is being provided with the air blast of in the oven dry storehouse, blowing; The air outlet that is installed on feed end place, the elementary oven dry storehouse end face links to each other with said hair-dryer; Adverse current wind distances zone face height in the drying chamber generally between 10cm-20cm, wind speed 10 meter per seconds-16 meter per second.The air-flow that air blast is blown in the drying chamber is discharged in dewatering station; What carry out is the air-dry operation of reverse high speed, and the moisture removal rate on dry fruit surface further reaches 99%, and also can keep suitable moisture in the dry fruit pulp; Thereby guarantee dry fruit after a series of processed of process, mouthfeel is neither too hard, nor too soft.
(5) wind-warm syndrome that is blown in secondary oven dry storehouse from air blast is controlled at 30 o-45 oBetween, best wind-warm syndrome is 30 oFor the cold conditions in winter, air heating apparatus can be installed in the air blast front.
As a kind of preferred version, the adverse current wind distances zone face height in the drying chamber generally between 12cm-15cm, wind speed 12 meter per seconds.
