In order to ensure the pure flavor, delicate taste, safety and hygiene of pineapple juice, a series of equipment is required in the production process of pineapple juice. Below we list some of the main equipment used in pineapple fruit juice processing.
1. Pineapple cleaning machine
Used to remove dirt and dust from the surface of pineapples to ensure the hygiene and product quality of subsequent processing. The common form is bubble cleaning machine + brush cleaning machine.
Precautions for use:
The water source needs to be clean, and it is best to be equipped with a circulating water treatment system.
Replace or filter the cleaning water regularly to prevent secondary pollution.
The cleaning intensity should be moderate to avoid damaging the peel and causing juice loss.
2. Peeling and core removing machine
Automatically removes the rough peel and hard core of pineapple to improve processing efficiency and product quality.
Precautions for use:
The size of raw materials should be basically consistent to avoid equipment jamming or incomplete peeling.
The knife should be kept sharp and cleaned regularly to prevent bacterial growth.
The peeling thickness can be adjusted to reduce pulp waste.
3. Juicer
Crush and squeeze the peeled pineapple to extract the juice. Common equipment includes spiral juicer or belt juicer.
Precautions for use:
Raw materials should be evenly fed in to prevent blockage or overload.
The equipment should be thoroughly cleaned after each use to prevent the fermentation of pomace and the generation of odor.
4. Vacuum degasser
Remove oxygen and some volatile substances from juice to prevent oxidation, discoloration and taste change of juice and extend shelf life.
The vacuum degree and temperature must be well controlled to avoid loss of flavor components in juice.
The equipment must be well sealed to prevent air from entering.
5. Sterilization equipment
Kill microorganisms in juice to ensure product safety.
Precautions for use:
Sterilization temperature and time must be strictly controlled, generally 85-95℃, lasting 15-30 seconds.
Automatic temperature control and alarm system should be equipped to prevent overheating.
The production of pineapple juice requires close cooperation of equipment in all links, from cleaning, peeling, juicing, to degassing, sterilization, and filling. Each device not only improves production efficiency, but also ensures product safety and quality.
