Why Build Yam Chips Production Plant

Yam is a good source of carbohydrates, vitamins, and mineral salts, besides several components that serve as raw materials for medicines. So yams as the edible food in people’s daily diets can bring lots of health benefits, which is increasingly favored by people in the world.
The harvest of yams generally is between 7 and 12 months after planting. When harvested, yams possess about 70% of moisture which can cause a fast deterioration in the atmospheric temperature. Thus it is difficult for yams’ storage and long-distance transportation.
Due to the great demand for yams and difficulty in storage, the yam processing industry develops fast in the world to prolong its storage, improve values, and balance yam seasonal and regional discrepancy. Crispy yam chip is one of the most popular yam processing ways to process fresh yams into snack chips. Yam chips production can not only bring a delicious snack in people’s daily life but also benefit your health. Obviously, building yam chips production plant is a necessary and profitable investment, and here is detailed information about building a yam production plant.

How to Build Yam Chips Production Plant

I. Choose Suitable Factory Site

1. The factory should be near the city or town, to facilitate the yam chips production and provide daily necessities.
2. It would be better than the factory is near a place with rich raw materials. And good transportation is also necessary.
3. Choose the site with a rich water supply to save refrigerating output. Yam chips production factory should be with enough electricity, so it should be near the thermal power station.
4. The site should be located in the downwind direction of the residential area and downstream of the river.
5.  The wastewater discharge and dilution should be taken into consideration in choosing the factory site.

II. Arrange Right Yam Chips Plant Layout

1. Meet Yam Chips Production Process Demand

According to the production flow process to arrange plant layout, raw materials can be processed continuously in the horizontal and vertical directions, to minimize the production line from raw materials to finished products. Save production pipes, lower the investment and bring good economic effect.

2. Unified Design

Machines should be arranged in unified design to form a concentrated operation platform, avoiding increasing building components & floor area and enlarging the investment. The workplace will be tidy and clean.

3. Reasonable Facility Layout

Arrange well the location of the factory entrance, passageway, and stairs. Factory gates should be set apart from other facility gates. The width & height of the factory gate should be over 0.2m wider than that of the widest equipment.

4. The Layout of Substation and Distribution Room

The substation and the distribution room should be located in the upwind direction, and be near the equipment with much energy consumption to avoid energy loss.

5. Reserved Field

The expansion area should be reserved in the factory design.

III.Purchase Equipment Applied in Chips Production

Brush type cleaning & the peeling machine is suitable for yam. Yams are relatively soft, brush-type machine not only peels yam also brings no harm to them.
Picking line
The picking line can pick well-formed ones and then transport them to the cutting machine. It is widely used in the food processing lines, suitable for various kinds of food.
The yam slicing machine has two feed designs including vertical feeding and side feeding. Based on capacity, we have various models to cut different capacities and thicknesses of 0.5-10mm. It is also applied for cutting carrots, potatoes, lotus, and so on.
The blanching machine is for pre-cooking yam chips. The blanching time can be adjusted by changing convey belt running speed. And there are three models for chips processing.
The dehydration machine adopts the centrifugal principle and removes food surface water through the fast rotating barrel. Four capacities are available: 8-10kg/time, 15-20kg/time, 25-30kg/time and 35-40kg/time.
The frying machine is designed for frying chips also for frying nuts, fruits like peanuts, puffed food, etc. The frying time is about 1-2 minutes. Two discharging methods can be chosen: manual type and automatic type.
The deoiling machine can offer a quick deoiling and cooling process. Equipped with an anti-shock system, the deoiling machine can operate stably at high roasting speed.
With a flavoring machine, customers can season diversified flavors totally based on their demands. There are two types of seasoning machines: octagonal type, and roller type. Besides, the diameter and length of the rolling drum seasoning machine can be customized according to your need.
The mufti-functional packing machine can realize both nitrogen filling package and vacuum package. Yam chips should be packed in nitrogen-filled bags. And other meat products and blanched vegetables are packaged in vacuum bags.
The elevator is the auxiliary equipment in the processing line, used for material feeding to connect two machines, ensuring complete production.

IV. Build Complete Yam Chips Production Line

Before beginning yam chips production, you should choose good quality raw materials. Choose straight, thick and fresh yams and remove malted and rotten ones. The chips production line should strictly follow these steps:


1. Cleaning and Peeling

Put yams into the washing and peeling machine for washing off the mud and sand on the yam surface, removing yam peels. Cleaning and peeling is a vital step to reduce impurity pollution and pesticide residues.

2. Picking

Pick out the yams relatively uniform in size by the picking line and send them to the cutting machine.

3 Slicing

Yams are transported into a slicing machine for cutting into uniform slices. Yams can be cut by the slicer in different thicknesses and shapes to meet various demands.

4. Blanching

Blanching is a necessary part as it can protect materials’ natural flavor from being broken. Yam chips are put into boiling water for a few minutes and then plunged into cold water. During blanching, yam chips’ flavor, color, texture, and nutritional value are altered. Water blanching minimizes the leaching of solid, which leaves more natural sugars in products and it improves flavor retention and color retention to produce a final product with superior flavor, texture, and color.

5. Dehydration

Yam chips are put into the dehydration machine to remove the surface water from the slices. with the centrifugal principle and the fast rotating barrel, chips are dehydrated.

6. Frying

Dehydrated chips are fried in the frying machine. Oil on the top to fry food and water at the bottom to receive waste, which actually can keep oil clear and reduce the oil-wasting.

7. Deoiling

Fried yam chips are put into the rotatable screen drum in the cabin. With the wind from the bottom, fried chips turn over under the centrifuge force. High-pressure airflow blows away the surface oil and cools down chips. The extra oil that is blown out is dropped out with centrifuge force, flowing out from beside the pipe. You can place a bucket to collect them.

8. Flavoring and Cooling

For better taste, a chips seasoning machine is applied. Chips are rotary in the drum and different flavors are added, thus chips and flavor are mixed evenly, then discharged from the machine automatically. Then chips will be cooled by air cooling.

9. Packing

After seasoning and cooling, chips will be packed by the packing machine. Weigh, pack and store.
