Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine processing technology, and in particular to an integrated device and method for superheated steam blanching and drying of Gardenia jasminoides. Background Technology

[0002] Gardenia jasminoides Ellis, a plant in the Rubiaceae family, is a dried, ripe fruit. It has the effects of purging fire and relieving irritability, clearing heat and promoting diuresis, cooling blood and detoxifying. It can be used for febrile diseases with irritability, damp-heat jaundice, painful urination due to heat, bleeding due to blood heat, and heat toxicity syndrome.

[0003] Drying is an important processing method for extending the shelf life of gardenia and extending its value chain. However, its dense waxy surface layer inhibits the removal of internal moisture, leading to problems such as long drying time, severe color deterioration, and serious degradation of active ingredients. Existing technologies often use blanching pretreatment to break down the waxy layer of gardenia skin to improve drying efficiency and product quality. Generally, hot water or steam blanching is used, followed by spreading or independent drying equipment. This segmented processing has obvious drawbacks: First, material transfer between processes leads to large heat loss, long processing cycle, and high labor costs; second, hot water blanching easily leads to the loss of water-soluble nutrients and is difficult to treat, while steam blanching has low heat transfer efficiency and poor uniformity; in addition, hot water or steam blanching easily produces water vapor condensation, which increases the moisture content of the material and is not conducive to subsequent drying; third, the blanching and drying process parameters are not consistent, and temperature and humidity control is difficult to precisely coordinate, affecting the uniformity and quality stability of the finished product.

[0004] In view of this, how to provide an integrated device for blanching and drying gardenia fruit that can overcome all or part of the above-mentioned defects is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0009] Furthermore, the heat pump heating system includes: An evaporator, located in the upper chamber, has a cooling fan, the air outlet of which is located outside the housing; A condenser is disposed in the middle chamber, and a compressor connected to the evaporator and the condenser is disposed in the middle chamber. An expansion valve is disposed between the evaporator and the condenser.

[0010] Furthermore, it also includes a dehumidification system, which comprises: An axial flow fan is installed on the lower surface of the upper partition, with its outlet located in the upper chamber. It is used to push the residual high-temperature and high-humidity gas towards the exhaust port to improve the dehumidification efficiency.

[0011] Furthermore, a condensate collection tray is provided on the bottom surface of the lower chamber, and the outlet end of the condensate collection tray extends outside the housing to discharge the water condensed by the heat pump system outside the housing.

[0015] This invention also provides an integrated method for superheated steam blanching and drying of Gardenia jasminoides, using an integrated device for superheated steam blanching and drying of Gardenia jasminoides, including the following steps: S1: Start the centrifugal fan and electric heating tube to preheat the air in the blanching and drying chamber, lay the material on the material tray, put it into the blanching and drying chamber, and embed the sensing end of the PT100 temperature sensor into the material. S2: Open the manual valve and solenoid valve, and superheated steam enters the steam distribution chamber. It is then sprayed onto the material through multiple exhaust pipes to kill the green. The temperature and humidity of the killing and drying chamber are monitored in real time by a temperature and humidity sensor, while the material temperature is monitored by a PT100 temperature sensor. S3: After the blanching is completed, close the solenoid valve, turn on the heat pump heating system, centrifugal fan, axial fan and dehumidification fan to exhaust the high temperature air in the blanching and drying chamber from the dehumidification port. After the dehumidification is completed, turn off the axial fan and dehumidification fan and start the drying process. S4: During the drying process, the condenser releases heat to heat the air, and the evaporator absorbs heat accordingly. The cold air generated by the evaporator is discharged through the cooling fan. Under the action of the centrifugal fan, the heated air passes through the electric heating chamber, the air chamber, and the hot air injection pipe in sequence, and then is injected onto the material. After exchanging heat with the material, the air enters the upper chamber and the middle chamber through the return air port, and exchanges heat with the condenser again, so that the air circulates in the hot circulation channel to dry the material. S5: In step S4, when the temperature and humidity sensor detects that the temperature of the blanching and drying chamber is higher or lower than the set temperature by 2°C, the control box correspondingly reduces or increases the frequency of the compressor to restore the temperature of the blanching and drying chamber to the set temperature; when the temperature and humidity sensor detects that the humidity of the blanching and drying chamber is higher than the preset humidity, the axial flow fan and the dehumidification fan are started until the humidity of the blanching and drying chamber returns to the set humidity; when the temperature and humidity sensor detects that the humidity of the blanching and drying chamber is lower than the preset humidity, the solenoid valve is started to humidify through superheated steam until the humidity of the blanching and drying chamber returns to the set humidity.

[0016] The present invention discloses the following technical effects: (1) The present invention integrates superheated steam blanching and jet impact drying into a single closed device. Gardenia can continuously complete the blanching and drying process on the inclined material tray, eliminating intermediate handling and waiting links, greatly improving processing efficiency. The inclined material tray can load more materials, reducing labor processing costs.

[0017] (2) The steam generator is connected to the chamber via a steam pipe. The solenoid valve can automatically control the steam discharge rate. Through the steam distribution chamber and multiple exhaust pipes, the steam enters the blanching and drying chamber more evenly and is directly sprayed onto the material surface, resulting in higher heat transfer efficiency and better blanching effect. Furthermore, the use of superheated steam for blanching has the advantages of high thermal efficiency, energy saving, and less material deformation and oxidation. Before blanching, the blanching and drying chamber is preheated by an electric heating auxiliary system to prevent condensation after the steam is introduced.

[0018] (3) The heat pump heating system is used as the main heat source, which has the advantages of energy saving, high efficiency and environmental protection. In addition, the residual heat in the drying chamber after blanching can be used for drying, which can reduce energy consumption and shorten drying time.

[0019] (4) Multiple sensors are used to monitor the temperature, relative humidity and internal temperature of gardenia in the blanching and drying chamber in real time during the gardenia processing, so as to quantify the blanching and drying process of gardenia. The temperature and humidity in the blanching and drying chamber are adjusted in real time through the control box to achieve precise control of the gardenia processing process, thereby improving the quality of gardenia processing.

10. A method for integrating superheated steam blanching and drying of Gardenia jasminoides, characterized in that, The integrated superheated steam blanching-drying device for Gardenia jasminoides as described in claim 9 includes the following steps: S1: Start the centrifugal fan (30) and electric heating tube (28) to preheat the air in the blanching and drying chamber (23), lay the material on the material tray (13), put it into the blanching and drying chamber (23), and bury the sensing end of the PT100 temperature sensor (16) into the material. S2: Open the manual valve (21) and the solenoid valve (19), and the superheated steam enters the steam distribution chamber and is sprayed onto the material through multiple exhaust pipes (17) to kill the material. The temperature and humidity of the killing and drying chamber (23) are detected in real time by the temperature and humidity sensor (12), and the material temperature is detected by the PT100 temperature sensor (16). S3: After the blanching is completed, close the solenoid valve (19), turn on the heat pump heating system, centrifugal fan (30), axial flow fan (5) and dehumidification fan (10) to discharge the high temperature and humid air in the blanching drying chamber (23) from the dehumidification port (9). After the dehumidification is completed, turn off the axial flow fan (5) and dehumidification fan (10) and start drying. S4: During the drying process, the condenser (4) releases heat to heat the air, and the evaporator (8) absorbs heat accordingly. The cold air generated by the evaporator (8) is discharged through the cold fan (6). Under the action of the centrifugal fan (30), the heated air passes through the electric heating chamber, the air chamber, and the hot air jet pipe (15) in sequence, and then is sprayed onto the material. The air that exchanges heat with the material enters the upper chamber and the middle chamber through the return air port (11) and exchanges heat with the condenser (4) again, so that the air circulates in the hot circulation channel to dry the material. S5: In step S4, when the temperature and humidity sensor (12) detects that the temperature of the blanching and drying chamber (23) is higher or lower than the set temperature by 2°C, the control box (2) correspondingly reduces or increases the frequency of the compressor (3) so that the temperature of the blanching and drying chamber (23) returns to the set temperature; when the temperature and humidity sensor (12) detects that the humidity of the blanching and drying chamber (23) is higher than the preset humidity, the axial flow fan (5) and the dehumidification fan (10) are started until the humidity of the blanching and drying chamber (23) returns to the set humidity; when the temperature and humidity sensor (12) detects that the humidity of the blanching and drying chamber (23) is lower than the preset humidity, the solenoid valve (19) is started to humidify through superheated steam until the humidity of the blanching and drying chamber (23) returns to the set humidity.
