1、 The raw materials should be fully mature, fresh, with good flavor, rich juice, and free of diseases and insect pests, and those with insufficient maturity should be ripened after ripening.
2、 Raw material pretreatment
2.1. Cleaning. After the raw materials are selected, they are washed with clean water, and then rinsed in 1% hydrochloric acid solution or detergent solution to remove residual pesticides, and then rinsed in clean water and drained.
2. It was carried out by cutting and half digging machine. 3. Soak for color protection. 1% of the raw material after cutting and half digging the core. Soak in the mixture of ascorbic acid and citric acid for color protection.
3、 The pulp is heated at 90 ℃ – 95 ℃ for 3-5 minutes to promote softening. The pulp is beaten by a beater with a diameter of 0.5 mm to remove the peel.
4、 In order to increase the flavor of the pulp after the previous step, it needs to be adjusted. Sugar, citric acid and L-ascorbic acid are added in the adjustment. The ratio was 100kg peach pulp, 80kg 27% sugar, 0.45kg citric acid and 0.07-0.2kg L-ascorbic acid.

5、 Homogenization degassing homogenization is to make the suspended pulp particles of the juice split into smaller particles and evenly disperse in the juice, so as to increase the stability of the juice and prevent stratification. The homogenization method is to pass the coarse filtered juice through a high-pressure homogenizer, so that the pulp particles and colloidal substances in the juice pass through a small hole with a diameter of 0.002-0.003 mm under high pressure and become smaller particles. Generally, 130-160 kg / cm2 homogenizer is used in production. In addition, colloid mill can be used for homogenization. When the juice flows through the slit with the clearance of 0.05-0.075 mm, the pulp particles in the juice will collide and rub with each other due to the strong centrifugal force, so as to achieve the purpose of homogenization. In the process of fruit juicing, oxygen, nitrogen and carbon dioxide enter into the fruit. Among them, nitrogen can cause the oxidation of vitamin C and pigment. Therefore, degassing is necessary.
6、 It takes only 6-7 seconds to heat the canned juice to 100 ℃ for instant sterilization at 120 ℃. Fill the tank immediately while it is hot. 7、 Seal, cool, screw the cap tightly and invert the jar for one minute. After sealing, it was cooled to about 38 ℃ in sections and stored in storage. The qualified fruit tea product is pink or yellowish brown, dark red is allowed, the juice is even and turbid, there are particles precipitated after long-term standing, it has peach juice flavor, no peculiar smell, and the soluble solid content reaches 10% – 14%.

Beverage filling machine is a rotary bottle washing machine, which is mainly used for washing new bottles of beverage, water and other products. The bottle is then sent to the filling machine for filling the product. The PET bottle enters the equipment from the bottle dividing star wheel, and the bottle mouth is clamped by the clamp and the overturning mechanism, and the bottle mouth is turned downward. After the sterile water is washed, it is drained, and automatically turns over to the bottle mouth upward, and is transported to the filling machine through the bottle outlet star wheel. All of them are made of high quality stainless steel, and the main parts are stainless steel. The new stainless steel clamp has simple structure and convenient adjustment; the contact area with the bottle mouth is small, which can effectively avoid the secondary pollution to the bottle mouth. The bottle washing machine is equipped with a water receiving plate to recover the bottle flushing water. When the bottle is flushed, the flushing volume of each bottle is 105ml / S (at 0.25MPa)

The filling part can fill the materials into the washed bottles sent by the bottle washing machine. Filling machine is our company’s own design, filling valve has independent intellectual property rights, the use of pressure filling negative pressure reflux principle. The filling valve adopts the way of pressure filling negative pressure reflux, which makes the filling fast and sensitive, and the filling liquid level precision is high. There is no spring in the valve, and the material does not contact with the spring, which is conducive to cleaning the inside of the valve. In order to ensure the filling process and filling temperature, the material in the valve is in micro reflux state when there is no bottle or shutdown. The filling cylinder is full to ensure the stable pressure in the cylinder. The whole machine has perfect CIP cleaning interface. The double guide rod bottle lifting structure is adopted to make the bottle lifting and centering stable. The main drive adopts gear transmission, that is, open combined transmission, with high efficiency, low noise, long service life, convenient maintenance and sufficient lubrication. The main motor speed of the machine is controlled by frequency converter, and the machine adopts stepless frequency conversion speed regulation. The bottle guiding system is simple in structure and can be changed quickly and conveniently according to the bottle type. The whole machine adopts the bottleneck structure. PLC automatic control, fault on-line display, such as bottle blockage, lack of cover, etc. The key parts and electrical components of the machine are imported products.

In the capping part, the lid arranged by the capping device is screwed onto the bottle of the filled product and sent to the next process by the conveyor chain. The capping machine drives the rotary disc to rotate through the reducer. The centrifugal force from the bottom of the hopper leaves the cover. There is a positive and negative cover separation device at the outlet. When the reverse cover passes by, the cover will fall into the return pipe automatically, and the reverse cover will be blown into the hopper automatically by wind power. Only the positive cover can enter the slide smoothly. The cover quantity in the hopper is automatically detected by the photoelectric switch to control the cap conveying machine, so as to ensure the ideal effect of the lower cover. When the front cover enters the slide, it can enter the feeding plate smoothly. In order to prevent accidents, an anti reverse cover dial is set on the slide at the same time to ensure that the cover entering the feeding cover plate is correct. A pair of photoelectric switches are also equipped on the slide. When no cover is detected, the main engine will be stopped immediately. In order to effectively remove the damaged cover without anti-theft ring and the remaining cover when cleaning the hopper, there is a movable outlet opposite the hopper outlet to meet this function. Screw cover is magnetic screw cover, with overload protection function, and screw cover torque is stable and reliable. There is no gnawing cover, high cover, crooked cover and curling.
