They are high in sugar, rich in protein, fat, and minerals such as phosphorus, iron, and calcium. Jujubes contain a large amount of vitamins A, B, C, and P. Every 100 grams of fresh jujubes contains 400-600 mg of vitamin C, which is the highest among all fruits. Fuping jujubes are also important Chinese medicinal materials and tonics, which have the functions of promoting body fluid, moistening the lungs, nourishing blood, calming, nourishing the liver, and strengthening the stomach and digestion.

[0042] Step 2: Wash the red dates with running spring water to remove dust and residual pesticides on the surface; ensure the quality and hygiene safety of the red dates.

[0043] Step 3: After thorough cleaning, place the red dates in a special steamer, add an appropriate amount of liquid made from Chinese medicinal materials such as astragalus, ganoderma lucidum, and spiny jujube seeds as a steam source, and steam for the first time; during the steaming process, maintain appropriate temperature and pressure to ensure that the shape and nutrients of the red dates are not lost; initially soften the red dates and guide the effective ingredients of the Chinese medicinal materials to penetrate. Increase the health function of the product. Generally speaking, the specific time can be adjusted according to the number and size of the red dates.

[0044] Step 4: Dry the steamed red dates; change the traditional drying method and adopt modern drying technology to avoid the intrusion of outdoor dust and impurities, and avoid contamination by flies, mosquitoes and bacteria.

[0045] Step 5, repeat the steaming and drying steps of step 3 and step 4 above for multiple times; use the steam containing Chinese medicinal materials again to enhance the absorption of medicinal ingredients by red dates. After three steaming and drying, ensure that the red dates reach an ideal dry state, and at the same time, the effective ingredients of the medicinal materials are retained and integrated to the greatest extent. Then perform shaping, disinfection and sterilization, and finally package. Steaming time: Each steaming time must be strictly controlled within a reasonable range to ensure that the red dates are fully softened without breaking. Drying conditions: Control the time according to the amount of the item to ensure that the red dates reach an ideal degree of dryness. Amount of Chinese medicinal materials: The amount of Chinese medicinal materials must be appropriately adjusted according to the amount and quality of the red dates to ensure that its medicinal ingredients can fully penetrate into the red dates. Generally speaking, the amount of Chinese medicinal materials should not be too much so as not to affect the original flavor and taste of the red dates. After multiple steaming and drying, the nutrients in the red dates are fully released and concentrated, such as vitamins, minerals and dietary fiber. The red dates made by the present invention are easy to digest and absorb: multiple steaming helps soften the red dates, making them easier to be digested and absorbed by the human body. The water content in the red dates is reduced, and the nutrients are more concentrated, which helps to improve the nutritional value. Unique taste: The three-steaming process makes the red dates softer and more delicate, while retaining the natural sweetness of the red dates. The flavor of the red dates is richer and the taste is more unique. Easy to store and transport: After multiple dryings, the water content of the red dates is greatly reduced, which is convenient for long-term storage and transportation.

6. The red date steamer device according to claim 5, characterized in that: The cooking box (19) is provided with a pressure gauge (28) for detecting the internal pressure thereof.

7. The red date steamer device according to claim 5, characterized in that: The side wall of the cooking box (19) is also provided with a heating and drying pipe (29), the top of the cooking box (19) is provided with an exhaust pipe (30), and the exhaust pipe (30) is provided with an electric control valve (31).

8. The red date steamer device according to claim 5, characterized in that: The cooking box (19) is provided with a storage mechanism in the non-drying room for storing the heating and drying tube (29).

9. The red date steamer device according to claim 8, characterized in that: The storage mechanism comprises a telescopic cavity (32) which is arranged on the inner wall of a cooking box (19) and is recessed inwardly, and a telescopic plate (33) which moves along the telescopic cavity (32) is arranged in the telescopic cavity (32), the heating and drying tube (29) is arranged on the surface of the telescopic plate (33), and a sealing end plate (35) which is used to seal the port of the telescopic cavity when the telescopic plate (33) is retracted into the telescopic cavity (32) is also installed on the telescopic plate (33), and a telescopic cylinder (34) which drives the telescopic plate (33) to perform telescopic movement along the telescopic cavity (32) is installed on the cooking box (19).

10. A red date steamer device according to any one of claims 2 to 9, characterized in that: The working method of the steamer device is as follows: first, a medicinal liquid prepared from Chinese medicinal materials such as astragalus, ganoderma lucidum, and spiny jujube seeds is put into a steam generating device as a steam source, the Chinese medicinal liquid is heated by a heating pot, the Chinese medicinal liquid is heated to a suitable temperature, and the heated medicinal liquid is pumped into a nozzle on a spray rack by a circulating pump, and sprayed toward a heating tube, and the sprayed medicinal liquid is heated by a high-temperature heating tube to generate a large amount of steam containing Chinese medicinal ingredients, and the steam enters a steaming device to steam red dates; during the spraying process, an anti-scaling cleaning mechanism is used to clean the surface of the heating tube, and the anti-scaling cleaning mechanism is provided on the outer periphery of the heating tube. The heating sleeve is mainly composed of a heating sleeve rotating along the heating tube, and the hydraulic pressure generated by the circulating pump is used to drive the impeller to rotate. The rotating impeller drives the heating sleeve to rotate through the transmission shaft. The cleaning wire layer on the cleaning plate is used to clean the surface of the rotating heating sleeve to prevent the Chinese medicine liquid from forming a scale layer on the surface of the heating sleeve. After the steaming is completed, the red dates are dried by the heating drying tube. At the same time, a storage mechanism is set in the steaming box, so that the heating drying tube can be stored during the steaming, so that the steam will not damage the heating drying tube. When drying, the heating drying tube is pushed into the steaming box to dry the steamed red dates.
