Tapioca Fufu Processing Line Extract From Tapioca

Process flow

1. Raw material receiving impurity removal unit:

Dry soil remover: The fresh tapioca are transported to the raw material storage yard of the factory by trucks with a load of about 5-10 tons, and the tapioca raw materials are transported to the raw material receiving warehouse by forklifts or manually, and are unloaded by the vibrating feeder to the belt conveyor, it is transported by the belt to the drum soil remover for preliminary dry impurity removal to remove impurities such as sand, rhizomes, grass stalks and bark on the tapioca raw materials.

2. Tapioca cleaning and peeling unit:

(1) Paddle washing machine: The raw materials after dry impurity removal enter a set of two-stage series paddle washing machines to wash the tapioca with water to remove the residual sand and broken skin, to ensure that the raw materials entering the filing and grinding section are washed of. The main function of the front part of the washing machine is to fully soak the raw materials, so that the tapioca is removed by mutual friction and stirring. The raw materials are sent to the clean water tank of the next level through the water tanks in different areas, and the clean washing water is added to the washing machine behind, so that the tapioca is cleaned by the countercurrent cleaning method.

(2) Brush cleaning and peeling machine: In order to ensure that the raw material skin impurities are cleaned as cleanly as possible, a brush cleaning and peeling machine is added to remove the tapioca skin and difficult-to-remove impurities.

(3) Drum spray cleaning machine: The tapioca raw material after brush cleaning is transported to the drum spray cleaning machine through the belt conveyor for further cleaning, and the impurities such as skin, sediment and other impurities doped on the surface of the material are cleaned by spraying as much as possible. The material is then conveyed to the crushing unit through the belt conveyor.

3. Crushing and sand removal unit:

(1) Preliminary crushing: Due to the large size of tapioca tubers, preliminary crushing is required before crushing. The completely cleaned tapioca raw materials are transported into the crusher and cut into pieces of about 10mm in size, and the crushed tapioca pieces enter the crusher. , further crush the tapioca.

(2) Filing and pulping: the disintegrator rasps the tapioca pieces into tapioca slurry, which includes free starch granules, fibers, fibers containing bound starch and cell fluid (containing soluble substances such as protein, sugar and minerals). It needs to be diluted with process water during the filing and grinding process. After filing, the tapioca slurry enters the collecting tank through the screen under the filing machine and flows into the tapioca slurry barrel. A slurry pump is installed at the bottom of the tapioca slurry barrel, and the tapioca slurry is pumped into the de-sanding cyclone through the slurry pump to remove sand from the tapioca slurry.

(3) Fermentation: The mashed tapioca slurry is pumped from the pulp barrel into the fermentation tank for fermentation treatment, and then sieved by a centrifugal sieve after the fermentation is completed;

4. Centrifugal screening unit:

The tapioca pulp after filing and de-sanding is used to separate the fibers and starch contained in the pulp as much as possible through a centrifugal sieve, and the large fibers contained in the tapioca pulp are removed through a dewatering centrifugal sieve.

5. Press dewatering unit:

(1) Plate and frame filter press: The pulp in the tapioca slurry temporary storage tank is transported to the plate and frame filter press for dehydration and pressing through the feeding screw pump.

(2) Filter cake crusher: The pressed filter cake is crushed and broken into powder by the crusher, and then sent to the flash drying unit through the screw conveyor for drying.

6. Flash drying unit:

Flash dryer: The crushed filter cake is transported to the feed hopper of the ejector of the flash dryer through the screw conveyor, and then enters the flash dryer through the lifter for drying.

7. Screening storage unit:

Shaking sieve: After drying, the starch is sieved through a starch shaking sieve and then enters the starch finished product warehouse.

8. Weighing and Packaging:

Packing machine: according to the specifications required by customers, a ton charter machine and a small packing machine can be selected for packaging and storage.
