How do you calculate sugar mill capacity?
Mill Capacity Calculations
- c. is a factor dependent on the cane preparation equipment, c. = 1.3 if the tandem is preceded by a shredder.
- n. is the mill speed in rev/min.
- N. is the number of rollers in the tandem.
- L. is the length of the roll in metres.
- D. is the mean diameter of the rollers in metres.
- f. is the fibre percent cane.
How is Pol calculated on a cane?
Abstract : The following formulae are proposed: pol in cane = P(100 – P)/(100 – F); pol in cane (reduced to 12.5% fibre) = P(100 – (P/87.5)), where P = pol % primary juice, F = fibre % cane.
What is Java ratio in sugar industry?
The method of determining the sucrose content of each individual consignment of cane, is the so- called “Java Ratio” method. The sucrose percentage of the consignment is then arrived at by multiplying the sucrose per cent. crusher juice by the Java Ratio.
How do you find the heat surface area of an evaporator body?
Heating surface requirement for evaporator bodies as per E. Hugot formula. Heating surface requirement= vapour production/ ΔT * coefficient of heat transfer. (Note: In this table considered the parameter liquid column height in the body, Brix of the body and temperature of the liquid in that body.
How do you calculate sugar recovery?
Sugar recovery was calculated with the following formula (Mathur, 1981). J = Juice purity • M = Molasses purity Weight of sample + wt. lost during preparation. Moisture losses = Weight of original sample – Weight of oven dried sample.
What is mill capacity?
Abstract. The grinding capacity of a mill depends upon the grinding mechanism and the operational conditions. The absolute rate of breakage or the mill capacity is conventionally given as the product of the selection function and a powder hold-up (or a fractional volume of powder filling).
How do you calculate commercial cane sugar?
The commercial cane sugar percentage (CCS%) was calculated by using following formula (Meade and Chen, 1977). CCS % = {Sucrose % – (Brix % – Sucrose %) X 0.4} X 0.74 (Eq. 2) where, 0.4 = multiplication factor, 0.74 = crusher factor.
What is Brix in sugarcane?
The Brix percentage is a measure of the sucrose, or sugar content. One degree Brix is equal to one gram of sucrose in 100 grams of solution. Sugarcane with a Brix percentage closer to 23% Brix is considered to produce the highest quality of cane sugar.
How is evaporator capacity calculated?
Manufacturers size evaporators in terms of tons, a unit of power equal to 12,000 British Thermal Units (BTUs) per hour. This answer is the evaporator’s size, measured in BTUs per hour. Divide the answer by 12,000: 2,800,000 / 12,000 = 233.33. This answer is the evaporator’s size in tons.
What is the formula for the capacity of evaporator?
Explanation: Economy of an evaporator is defined as, E = Capacity/Consumption = (30/45) x 100 = 66.7 = 67%. 4. What is the Evaporator Consumption if we evaporate 10kg of water from a feed of 50kg at a temperature of 25℃ to a final temperature of 100℃ in an hour? Hence the Evaporator Consumption = 20kg/hr.
