Q1. The most common machine used for paddy hulling in India is?

1. Husk Separator
2. Rubber–Roll Sheller
3. Engle berg Huller
4. Under Runner Disc Huller

ANSWER: 3. Engle berg Huller

• Explanation: The “Engle berg” huller is the most prevalent paddy hulling machine in India. This machine’s main component is a ribbed cast-iron roller. Inside a huge concentric cylinder, the roller rotates on an axis. The husk and bran are scraped off due to friction between the grain and the steel elements of the huller. The huller conducts both husking and bran removal at the same time.

Q2. In __________ the vapour is condensed and then re-evaporated when a further separation occurs.

1. Fractional distillation
2. Cold dehulling
3. Temperature Sensitivity
4. Wet dehulling

ANSWER – 1. Fractional distillation

• Explanation – The vapour is condensed and then re-evaporated when a further separation occurs in fractional distillation. It is difficult, if not impossible, to manufacture pure components in this manner, but if the volatilities are sufficiently varied, a degree of separation can be easily achieved. Several distillations may be utilized when extreme purity is required.

Q3. In the _______ type of unit, a compressive force is applied by pressing the pulp between heavy rollers.

1. Screw Press
2. Roller Press
3. Hydraulic Pressing
4. Single-stage extractors

ANSWER – 2. Roller Press

• Explanation: Roller pressing applies a compressive force to the pulp by pressing it between heavy rollers. To improve the separation of liquid from solid, modifications to this approach have been devised. Simple crushing rolls, such as those used to extract sugar cane juice, feature drainage grooves (Menchaerts groves) on the roller surfaces. The liquors are directed away from the crushed cake by these grooves, which reduces re-wetting.

Q4. The method of expressing the liquid from the solid-liquid matrix include?

1. Hydraulic pressing
2. Roller pressing
3. Screw pressing
4. All of the above

ANSWER: 4. All of the above

• Explanation – Hydraulic presses are widely used in fruit juice processing whereas roller presses have not really been accepted. Roller presses are universally used in expressing juices from sugar cane. Screw presses are being used in fruit juice expression but here they tend to be used as ‘finisher’ following a prior pulp thickening process using other thickening techniques.

Q5. ________  is used for the extraction of juice from peeled fruits.

1. Fruit juicer
2. Fruit Mill
3. Fruit pulper
4. Fruit Press

ANSWER: 1. Fruit juicer

• Explanation: The fruit juicer is made of an all-aluminum body with a stainless steel sieve and is used to extract juice from peeled fruits. The Hand Operated Fruit Juicer is easy to clean and maintain and can be used continuously. These machines are also simple to operate and do not require any electricity or power because they operate on the same concept as a press machine. The product comes in a range of styles and models.
