Mango Juice & Pulp Processing Plants

A mango juice and pulp plant turns ripe, fibrous, stone-bearing fruit into pulp, puree or juice, and the variety, ripeness and fibre of the fruit decide the pulper, the screens and the heat treatment.

Mango Juice & Pulp Processing Plants

Most of the value sits in a thick, viscous pulp, so pumps and heat exchangers are chosen for body rather than for flow. A buyer has to settle three things first: whether the product is single-strength pulp, a thinner juice or nectar base, or a concentrate; whether it is packed aseptically into bulk bags, filled hot or held cold in tanks; and how many weeks of fruit the local season can really supply. Mango trees bear unevenly from year to year and the fruit keeps for only a short time, so supply is lumpy and a line sized for the peak week can stand idle for months. Peel, stones and fibre make up a large residue that needs a daily outlet, and that outlet belongs in the plant layout.

Mango arrives at mixed ripeness, so the first job is sorting to a uniform stage: under-ripe fruit is starchy and sharp, while over-ripe fruit is soft and ferments quickly. After washing, the fruit is either peeled and destoned before pulping, or crushed whole and passed through a screen that holds back skin and stone. Which route is used depends on the variety, because some skins carry an off-flavour. A pulper-finisher with a choice of screen sizes separates smooth flesh from fibre and skin fragments; finer screens give a smoother puree but leave more flesh behind on stringy varieties. Cut mango darkens through enzyme action, so a heating step before or at crushing stops browning, although the choice of treatment also moves colour and carotene retention. Deaeration removes air that would oxidise the pulp and cause foaming at the filler. The pulp is then heat-treated in a tubular or scraped-surface exchanger made for thick product, and is either filled hot, packed aseptically into bags in drums, or concentrated for a higher-solids product. Because the crop is seasonal, bulk pulp is often held cold and remade into juice or nectar outside the harvest, which makes cold storage and aseptic packing design items rather than extras.

Typical Process Route

1

Receiving and Washing

Fruit is weighed in, washed free of soil and sap, and kept in shade or a cool bay. Mango bruises and ripens quickly, so the time between harvest and the line is a control point.

2

Sorting by Ripeness

Rotten, damaged and under-ripe fruit is taken out and the rest is graded by ripeness. A mixed lot gives uneven colour and sweetness in the pulp.

3

Peeling or Whole-Fruit Pulping

Depending on the variety, fruit is peeled and destoned, or crushed whole and screened. Skin off-flavour on some varieties is the reason to peel, so decide this by trial on local fruit.

4

Enzyme Control

Heating the fruit before or as it is crushed stops browning. The harder the enzyme is stopped, the more care is needed to keep colour and carotene, so the setting follows the target product.

5

Pulping and Refining

A pulper-finisher separates flesh from fibre, skin pieces and stone fragments. Screen size sets texture, and stringy varieties need more cleaning than smooth ones.

6

Deaeration and Heat Treatment

Air is drawn off under vacuum and the pulp is heated in an exchanger built for thick product, which fouls faster than clear juice.

7

Concentration, Where Wanted

Pulp meant for concentrate goes to an evaporator that tolerates fibre and high viscosity; forced-circulation or scraped-surface types suit it better than a plain falling film.

8

Cooling, Filling and Cold Holding

Pulp is cooled and filled aseptically into bulk bags, hot-filled into cans or jars, or held in chilled tanks for remaking in the off-season.

9

Clearing the Residue

Peel, stone and fibre are removed continuously and sent to a feed or compost outlet before they ferment in the warm weather.

Process & Equipment Modules

  • Fruit receiving and washing unit
  • Sorting and ripeness-grading table
  • Peeler and destoner, where the variety needs peeling
  • Crusher with enzyme-inactivation heater
  • Pulper-finisher with changeable screens
  • Deaerator
  • Tubular or scraped-surface heat exchanger
  • Evaporator for fibrous pulp, optional
  • Aseptic filler or hot-fill line
  • Chilled holding tanks
  • Residue conveyor
  • PLC panel and temperature recorder

Plant Output

Mango pulp or pureeMango juice or nectar baseMango concentrate, where evaporation is includedStones, peel and fibre for livestock feed or compost

Applications

  • Single-strength mango pulp in bulk bags for off-season remanufacture
  • Mango puree sold to dairy, bakery and confectionery makers as an ingredient
  • Ready-to-drink mango juice and nectar for bottling or cartons
  • Mango concentrate as a beverage base
  • Fruit blends in which mango pulp is combined with pineapple or citrus juice
  • Pulp as the base for jams, fruit bars and fruit leather

Key Features

  • Screens to Suit the Variety

    A finisher with changeable screen sizes lets one line work smooth and stringy varieties and give each product the texture it needs.

  • Heat Exchangers Built for Body

    Thick pulp needs tubular or scraped-surface exchangers and positive-displacement pumps; ordinary juice plate units block quickly.

  • Enzyme Control Up Front

    Browning starts the moment fruit is cut, so the heating step sits at or before crushing, not after the pulp has sat.

  • Cold Holding for Bulk Pulp

    Chilled tanks or aseptic bags carry pulp across the off-season, and pulp held warm loses vitamins and antioxidants faster.

  • Residue Removed Without Stopping

    Stones, peel and fibre are a large stream; conveyors or pumps that take them away continuously keep the line running through the peak week.

Frequently Asked Questions

What information is needed to size Mango Juice & Pulp Processing Plants?
Fruit tonnage per week across the season and in the peak week, the varieties and how fibrous they are, the ripeness at arrival, the product (pulp, juice or concentrate), the pack type and the daily operating hours. Pulp content differs widely between varieties, so the same tonnage can give very different pulp volumes; a trial on the fruit you will actually buy is the best sizing input.
What capacity range does Mango Juice & Pulp Processing Plants cover?
The indicative capacity range is 500–10,000 kg fruit/hour. It is stated on a fruit basis per hour, so restate your own volume on that basis and say how many hours a day the plant will run.
Do mangoes have to be peeled before pulping?
It depends on the variety. Peeling costs time, labour and flesh, so many lines crush the whole fruit and strip skin and stone in a finisher. Some varieties carry an off-flavour in the skin and need peeling first. Run small trials with each variety you expect; the result decides whether a peeler and destoner is part of the plant.
How is browning of mango pulp stopped?
Heating the fruit before or as it is crushed switches off the enzyme that darkens cut flesh. The trade-off is that the treatment that stops browning most completely can also lower carotene retention, so a plant aiming at a bright puree may choose different settings from one making cooked-flavour pulp for jam. Agree the colour target with the pulp buyer first.
What happens to the peel, stones and fibre?
They form a large share of the fruit weight and ferment fast in warm weather. Most plants send them to livestock feed or compost, so line up a buyer or a farm outlet and a daily collection route before the first season, and cover the holding area.
How should a plant cope with a short, uneven mango season?
Size for the tonnage you can reliably buy, not the best week, and plan what the plant does afterwards: store pulp cold or aseptically for remaking, or run other fruit through the same pulper and heat treatment. See multi-fruit juice processing plants for a line that spreads the load across fruits.
Is it better to sell pulp or concentrate?
Single-strength pulp needs the least equipment and keeps the fresh character, but it carries a lot of water in freight and storage. Concentrate removes that water, at the cost of an evaporator that can take fibre and extra steam. The choice depends on your buyers and distances; see fruit juice concentration plants for the evaporator side.
