[0022] The color sorter 1 is used to perform preliminary screening on spice raw materials, remove impurities, discolored particles and other unqualified materials therein, and ensure the quality of the raw materials entering the subsequent processing steps.

[0023] The high-temperature steam instantaneous sterilizer 3 sterilizes the spices in a short time by using high-temperature steam, thereby reducing the contact time between the spices and high temperature and thus reducing the loss of volatile oil.

[0024] The high-temperature steam instant sterilizer 3 adopts steam instant sterilization technology and sterilizes spices using high-temperature steam provided by the steam input pipe 4. The high-temperature steam instant sterilizer 3 is provided with temperature and pressure sensors to ensure that the sterilization process is carried out within a suitable temperature and pressure range, the sterilization time is controlled within 2-10s, the temperature is controlled within 112-160°C, and the pressure is controlled within 1.5-6 atmospheres.

[0025] The steam input pipeline 4 can provide an input channel for high-temperature steam for the high-temperature steam instantaneous sterilizer 3 .

[0026] The waste steam output pipe 5 is used to discharge the waste steam after the high-temperature steam instantaneous sterilizer 3 is used.

[0027] The steam condensation essential oil extraction device 6 can condense the waste steam discharged from the high-temperature steam instantaneous sterilizer 3 to condense the volatile oil therein into a liquid state, thereby extracting the volatile oil in the spices and realizing the recycling of resources.

[0028] The ultra-low temperature pulverizer 7 can pulverize the sterilized spices in a low temperature environment, thereby avoiding the loss of volatile oils due to heat generated during the pulverization process and ensuring that the particle size of the pulverized spices meets the requirements.

[0029] The ultra-low temperature pulverizer 7 is provided with a refrigeration device or liquid nitrogen is added therein to control the pulverizing environment temperature between -20 and -50°C, and uses impact or grinding pulverizing cutters to ensure that spices can be effectively pulverized at low temperatures while avoiding the loss of volatile oils.

[0032] The screening machine 9 can screen the ground spices after the temperature is restored, and separate the products that meet the particle size requirements and the coarse particles that need to be crushed again.

[0033] The screening machine 9 adopts a vibration screening method, the mesh size is selected according to the particle size requirements of the spice product, and a defective material collecting device is provided at the bottom of the screening machine 9, which can return the defective material to the ultra-low temperature pulverizer 7 for re-pulverization.

[0035] The packaging machine 10 adopts automatic quantitative packaging technology and is set according to the packaging specifications of the product. The packaging materials are food-grade packaging materials to ensure the shelf life and sanitary safety of the spice products after packaging.

[0036] The working principle and operation process of the present invention are as follows:

[0037] First, place the spice raw material at the feed port of the color sorter 1, start the color sorter 1, remove impurities and heterochromatic particles in the raw material by color recognition and screening technology, and convey the screened spices to the high-temperature steam instant sterilizer 3 through the material conveyor 2. Open the valve of the steam input pipeline 4, and introduce high-temperature steam into the high-temperature steam instant sterilizer 3 to sterilize the spices instantly. The sterilization time is set according to the type and requirements of the spices. The waste steam generated during the sterilization process enters the steam condensation essential oil extraction device 6 through the waste steam output pipeline 5. The waste steam is condensed in the steam condensation essential oil extraction device 6 to condense the volatile oil therein into a liquid state and recover it through the collection device. The sterilized spices are sent to the ultra-low temperature pulverizer 7 by the material conveyor 2. Start the ultra-low temperature pulverizer 7 to pulverize the spices in a low temperature environment to ensure that the temperature is controlled at a low level during the pulverization process to prevent the volatile oil from volatilizing. The pulverized spices enter the low-temperature pulverized material temperature return device 8 and slowly return to a suitable temperature. The spices after returning to temperature enter the screening machine 9 through the material conveyor 2 for screening treatment, and separate the products that meet the particle size requirements and the coarse particles that need to be crushed again. The coarse particles can be returned to the ultra-low temperature crusher 7 for crushing again. The spices that pass the screening enter the packaging machine 10 through the material conveyor 2 for quantitative packaging to obtain finished spices.

[0038] The present invention reduces the loss of volatile oil in the spice during the sterilization process by coordinating the high-temperature steam instant sterilizer 3 and the steam condensation essential oil extraction device 6, improves the retention effect of volatile oil, and can recycle the volatile oil in the waste steam. The high-temperature steam instant sterilizer 3 can achieve efficient sterilization in a short time, ensure the sanitation and safety of spices, and improve the sterilization effect. The steam condensation essential oil extraction device 6 realizes the recycling of volatile oil in waste steam, and improves the resource utilization rate of the production line. The ultra-low temperature pulverizer 7 further ensures that the volatile oil is not destroyed during the pulverization process. The ultra-low temperature pulverization technology enables the spices to reach an ideal pulverization particle size under a low temperature environment, so that the spices are pulverized more evenly, the pulverization quality is improved, and it is beneficial to the application of spices in various industries.
