1、 Raw material selection
Select fully mature, fresh, good flavor, rich juice, no pests and diseases of fresh fruit, maturity is not enough to go through after ripening.
2、 Raw material pretreatment
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. Cut half and remove the nucleus. 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、 Heat beating
The fruit pieces were heated at 90 ℃ – 95 ℃ for 3-5 minutes to promote softening. The peel was removed by beating with a 0.5 mm diameter beater.
4、 Flavor adjustment
In order to increase the flavor of the pulp, it needs to be adjusted. Sugar, citric acid and L-ascorbic acid are added in the adjustment. The ratio is 100 kg peach pulp, 80 kg 27% sugar solution and 0.45% citric acid
0.07-0.2 kg of L-ascorbic acid.
5、 Homogeneous degassing
Homogenization is to make the suspended pulp particles of the juice split into smaller particles and evenly disperse in the juice 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. Production
Generally, 130-160 kg / cm2 homogenizer is used.
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 goal of homogenization.
During fruit juicing, oxygen, nitrogen and carbon dioxide enter the fruit, among which nitrogen can cause vitamin C and pigment
Therefore, degassing must be carried out.
6、 Sterilization canning
The juice was heated to 95 ℃ for 1 minute, and then canned immediately.
7、 Seal cooling
Tighten the cap and turn the jar upside down 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%.

(1) Choose eight or nine mature, no mildew, no damage, no decay juice, to clean the veins, melon meat color orange or yellow is better. Then clean, peel and seed, slice.
(2) Color protection. The melon slices were soaked in 0.1% VC and 0.15% citric acid for 5 min.
(3) Beating. The melon slices were beaten with a beater, and then treated with colloid mill and filtered for standby.
(4) Deployment. The fresh milk was filtered, the stabilizer, sucrose and emulsifier were fully dissolved and mixed with purified water and juice slurry.
(5) Add acid. Before adding acid, the temperature of the mixed solution is reduced to below 20 ℃, and then the pH value is adjusted to about 4.0 with citric acid.
(6) Homogeneous. The first homogenization pressure is 16MPa, and the second homogenization pressure is 20MPa.
(7) Degassing. The vacuum degassing method was used for degassing, the pressure was 0.06 ~ 0.08 MPa, and the temperature was 70 ~ 72 ℃.
(8) Sterilization. Pasteurization was used to sterilize juice milk beverage at 85 ℃ for 10 min.
(9) Cool down. Cool the product to about 20 ℃, then pack and refrigerate.
The glass bottle juice beverage production line is a full-automatic multi-functional combination unit integrating washing, filling and sealing. It is suitable for the automatic production of various glass bottle juice drinks.

a. Bottle washing part:
This machine is a rotary bottle washing machine, which is mainly used for washing new bottles of drinks, 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. The main structure of the equipment is made of high-quality stainless steel, and the contact part with the flushing medium and the external protective cover are made of high-quality stainless steel.
The new stainless steel clamp is simple in structure and easy to adjust; it has less contact area with the bottle mouth, effectively avoiding the secondary pollution to the bottle mouth
The bottle washing machine is equipped with a water tray to recover the bottle washing water
When the bottle is flushed, the water volume of each bottle is 105ml / S (0.25MPa)

b. Filling part:
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.
c. Screw cover part:
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.
