2. products description

1). NFC pineapple juice

While pineapple concentrate offers convenience and cost-effective transport, NFC pineapple juices are a more natural product which add premium quality to your finished product.

They are made simply by juicing the pineapple, then lightly pasteurising the juice to control the microbiological load. Nothing added, or taken away.

With such minimal processing, these NFC juices not only retain the vibrant flavour, colour and aroma of the pineapple, but also the excellent nutritional value.

2). Concentrated pineapple juice

Initially juiced in the same manner as an NFC pineapple juice, pineapple concentrate is then heated so that the fruit’s water content evaporates – resulting in a condensed solution six times the strength of a juice, but significantly smaller in volume.

The concentrate can then be transported more easily in larger quantities, before the water is re-added at the manufacturer’s end to bring it back to regular juice form.

5. Key machines’ description for pineapple juice processing line:

Key machines	Descriptions
Pineapple nylon brushing and spraying cleaning	1.Multi-pieces tapered brush rollers, friction the top and surface of the material at the same time.Staggered adjacent hair rollers run their own,fruits can be rotated 180 degrees.Full friction cleaning materials, no material stockpiling 2.With spray cleaning and water cycling system
Pineapple sorting machine	To select the defective fruit out and put them into the middle conveyor, then go to the waste conveyor. Smooth roller conveying make the fruit rotate along with the forwarding, which will generally avoid the choose negligence
Pineapple Chopping machine	The washed pineapples are chopped before going to the treatment line. The chopping dimensions depend on the required extraction (puree or pressed juice).
Pre-heater and enzyme deactivation machine	Used for deactivating enzyme and pasteurizing of crushed products and softening the fibers and to get consequently the maximum juice yield..;Adjustable temperature control and automatic return flow function.
Pineapple juice extractor	There are three different pineapple juice extractors for your choices: 1. Screw Extractor spiral juice squeezer for small capacity line: Screw juicer is suitable for squeezing the juice of crushed pineapple.The crushed materials enter the screw juicer through the feed hopper. As the bottom diameter of the screw gradually increases along the slag outlet direction, the pitch of the screw gradually decreases. When the material is pushed by the screw, the volume of the screw cavity shrink, forming a squeeze of the material. 2. Pineapple peeling and juice extracting --- refining machine This machine is mainly used to pre-process pineapple for juice. Its main function is to cut open, shove and separate the skins of fresh citrus which have been picked out and cleaned. Then the pulp is conveyed to the process of next . The materials don’t need to be graded. And it is frequency control of motor speed. After peeling and crushing machine, the pineapple pulp will go through a refiner to get homogenized juice. 3.Belt Type Juice Extractor This machine uses a plurality of pressing rollers to press the materials entering the filter screen. The machine has the characteristics of automatic feeding and discharging, continuous operation, full pressing, high juice yield and low moisture content of slag, which is widely used in the juice extraction process of fruits and vegetables.
Machines to add to produced clarified concentrated pineapple juice:
Pineapple juice Emzmolysis Tank	For high quality clarified pineapple juice, depending upon the application, clarification can be performed by an enzymatic treatment group followed either by Vacuum Filter or by Ultrafiltration. Both systems are designed to reach a very low degree of turbidity, preserving the organoleptic properties (color, taste, aroma, etc.) of fresh apples.
Pineapple juice Ultra-filtration	Ultrafiltration is a pressurized membrane separation technology. Under certain pressure, small molecule solute and solvent pass through the apertures of a special film, while the large molecules leave one side of the membrane. In this way, the large molecule content get purified. Ultrafiltration is a membrane separation technique that adopts pressure to separate large and small molecules.
Pineapple juice Evaporator	Falling Film Evaporator is applied to produce concentrated pineapple juice 1. Optionally, juice can be concentrated. Our Falling Film evaporator is particularly suitable for the production of concentrated carrot juices up to the BRIX values required by the market. 2. Forced circulation evaporator: Continuous concentration under vacuum and low temperature.
Pineapple juice Sterilizing and Aseptic Filling	1. The juice concentrated, can be sterilized or pasteurized depending by the specific request of the application, by a tubular heat exchanger. 2. In case of sterilization, the product can be filled in aseptic bag in drums or in box thanks to Aseptic Filling Machine (aseptic carton box, aseptic pouches...), while can be filled in drums or in any type of hot or cold filling machine (glass, PET, Can and BIB).
