2 Sorting
Remove pests, mildew and unqualified fruits with collision injuries, and remove mixed weeds, etc.
3 rinse
Rinse with running water to clean the surface sediment.
4 Fish out
Drain the carrots.


Peeling and pulping

Peel and soften raw materials

Prepare before work
Receive production supplies and utensils for the shift, wear work clothes, shoes and hats.
Clean and do an excellent job in the workshop machine obstacles and work, apparatus hygiene.
Check the normalcy of machines and equipment such as pre-boilers, crushers, juicers, centrifugal separators, etc., to ensure regular operation during production.
Check the connected pipes and strictly implement the CIP procedure of the pre-treatment workshop.

Peeling and softening

Drained carrots are peeled in hot soup.
Put the raw material into boiling water at 95℃ for 10 minutes hot scalding, fish out and rinse with flowing water; the skin will fall off naturally。 Then put the peeled raw material into the sandwich pot, turn on the steam cold felling and boil for 10 minutes and fish out.


Start the crusher, put the pre-cooked carrots into the crusher through the elevator and crush them, and use the low pot at the bottom to hold the catch.
Note: Water can be added appropriately when crushing to avoid blockage.


Batching, sterilization, filling and packing

Prepare material

Receive raw and auxiliary materials according to batch production instructions and check.
Check the appearance and report to the relevant departments in time if colour, flavour, or foreign matter is substandard and wait for processing.
Check that each package of self-matched ingredients received should be labelled with name code, date of ingredients and operator’s signature.

Preparation before operation

Receive production supplies and utensils for the shift, and put on work clothes, shoes and hats.
Check the machine working environment hygiene and clear the machine obstacles.
Check the machine and equipment, such as bottle machine, homogenizer, sterilizer, filling machine, coding machine, label shrinking machine, etc. To see if the various switches are regular to ensure regular operation during production.
Check the connected pipes and strictly implement CIP procedures.


Feeding according to production task requirements. Two people must be present during feeding to check the name (or code), and the feeder and checker should both sign on the production record. Sugar melting Add appropriate amount of pure water into the high speed mixing cylinder, heat to 80℃, add sugar and sugar ingredient A pre-mix, turn on the stirrer, heat to 95℃, and close the steam valve. Pour the sugar syrup into the stainless steel mobile tanker, add the appropriate amount of pure hot water, stir and dissolve, then pump into the high-speed mixing cylinder. Dosing A should be operated as follows:
  • Turn on the colloid mill switch.
  • Slowly pour the dosing A into the colloid mill hopper while slowly adding pure water.
  • Adjust the fineness of the colloid mill for micro-grinding.
  • Pump the colloid mill liquid into the portable tank car.
  • Set aside.
Open the valve, filtered by 200 mesh, and then pumped to the blending cylinder. Finally, use pure water to flush out the residual liquid in the high-speed mixing cylinder or sugar pot, filter and pipeline, and pump it to the batching cylinder for blending. Blending and fixing capacity Pump the beaten raw materials into the blending cylinder according to the added quantity. In the stirring state, slowly and evenly add all kinds of auxiliary materials in order. Finally, use pure water to fix the volume to the required measurement. Stirring time should be not less than 10 minutes. Note: (1) Each raw and auxiliary materials must be weighed and visually inspected before adding. (2) Make a good process record (3) When the material is put into the following process (cylinder), the water in the next cycle (cylinder or pipeline) should be drained; when the material is put into the batching cylinder, first open the discharge valve at the bottom of the batching cylinder. And after 5 seconds of material flow, close the discharge valve and carry out normal production. Testing Take a small amount of evenly mixed finished liquid, test its colour, odour, determine its total acid or PH value and refractive index value, and make records. The finished liquid whose index is not within the standard range should be adjusted. The refractive index should be changed by syrup. The total acid/PH value should be adjusted by citric acid, and records should be kept. Suppose the machine is shut down for more than 4 hours due to a power outage or mechanical failure. In that case, the material should be re-sensitized and physicochemically inspected. The material should be put into the following process only after passing the inspection.

Pipeline filtration

Open the duplex filter for filtration, fruit and vegetable juice, residual sweet juice filtered by 200 mesh.
When the filtration speed becomes slow, check whether the filter is blocked or broken, and promptly clean or replace the filter bag inside the duplex filter alternately.
Note: Check whether the filter mesh in the pipeline filter is replaced according to the regulations before each start-up. The same species of beverage requires the use of the same special filter mesh.


Open the cooling water, discharge valve and backflow valve of the homogenizer and check the lubricant level.
Start the homogenizer, and after the regular operation, open the 1-stage valve clockwise to make the pressure gauge needle swing slightly.
Adjust the 2-stage valve clockwise to make the gauge pressure to 1/3~1/4 process requirements.
Then adjust the 1-stage valve clockwise so that the gauge pressure to the pressure required by the process.
After the gauge pressure is stable, close the return valve and homogenize the material. At the same time, check the pipeline to confirm the state of the material.
Note: (1) When the machine is turned on, the 1st and 2nd stage valves should be relaxed, and the gauge’s oil pressure should be >.
(2) When turning off the machine, first loosen the 1-stage valve counterclockwise to no gauge pressure, then loosen the 2-stage valve counterclockwise, then turn off the power and turn off the cooling water.
(3) Homogenizing pressure is 30-35Mpa or depending on its specific requirements.
(4) Make a good record of the running process


Start the UHT instantaneous sterilization machine according to the “Sterilization Machine Operating Procedures”.
Start the feed pump, sterilize the material liquid material.
When the sterilization temperature rises to 121~130℃, the discharge temperature is 70~75℃, and the operation is regular, notify the filling machine for filling.
(1) materials before sterilization to ensure that the sterilizer and filling machine CIP cleaning is completed.
(2) materials into the following process (cylinder), the next cycle (cylinder or pipeline) in the water to drain. Materials will be played into the sterilizer material cylinder; first, open the discharge valve at the bottom of the sterilizer material cylinder. Wait for the material out 5 seconds, close the discharge valve, normal production. After sterilization, the reflux cylinder first opens the reflux cylinder bottom discharge valve, waits for the material out for about 15 seconds, and close the discharge valve to normal production.
(3) The whole process should be recorded in the “sterilizer operation record sheet”.

Filling and Sealing

Make sure the cap track is full of sterilized caps.
According to the product net content standard and comprehensive process factors, turn on the filling machine for filling and sealing according to the “Filling Machine Operation Procedures”.
When the filling starts, the first 80 bottles (300ml, 500ml) are not sealed, and 40 bottles (1000ml) are not sealed, and the finished liquid is poured into the reflux tank for recycling.
When the filling machine stops more than 5 minutes in the middle, 50 bottles (300ml, 500ml) and 35 bottles (1000ml) are not sealed. The sterilizer is stopped according to the operation when it starts filling.
Note: (1) Check the appearance of PET bottles when they are poured into the hopper of the bottle management machine.
(2) Filling should be complete, and the temperature of the centre of the bottle should be controlled at 70-75℃ after filling.
(3) The water temperature of the flushing mouth should be controlled at ≥65℃.
(4) Check the flushing nozzle regularly; it should not be blocked.
(5) Disinfectant preparation requirements:
A. Take the same weight of liquid A and liquid B according to the instructions (according to the concentration of 200ppm). Mix them for 5 minutes and then add pure water to prepare the disinfection solution with a residual chlorine concentration of 200ppm.
B. After the preparation, use a test paper to test to meet the specified requirements.
C. To be supplemented promptly according to the dosage.

Light Inspection

Check the bottle to the top of the cap, and check out the unqualified products such as an unscrewed cap, broken flying edge, insufficient liquid level, leaking bottle, debris inside the bottle, black spots on the bottle and other mechanical damage.
