Statement 1: The ingredients, mixing, filling, sealing and retorting are processes that are checked for safe and well carried out canning operations. Statement 2: The heat processes, cooling, handling and recording are processes that are checked for safe and well carried out canning operations.

Correct Answer: True, True
Both the given statements are true.

Give the correct sequence of steps involved in the process of receiving the supplies in a food service establishment.
1. Quality of ingredients are checked with specifications given to supplier.
2. Counts, weights or volume are checked to tally with amounts of various items on the delivery note.
3. Unacceptable items are returned with the person executing the delivery along with a note on delivery challan stating the items returned.
4. Delivery note is checked with copy of the order placed.
5. Delivery challan is countersigned by the receiving authority and the deliverer of supplies.

The mixing vat in a factory receives liquid ingredients through six separate value--- labeled R.S.T.U,Y and Z -- each of which has exactly two settings: open and closed.The mixing vat operator must ensure that each valve is set open or closed according to the following conditions: If T is open, both S and Z must be closed, R and Z cannot both be closed at the same time; If Y is closed, Z must also be closed;S and U cannot both be open at the same time. Which of the following, if given to the mixing vat operator as an instruction, would not determine the setting of any other valve ?

Concentrated fermentation liquid containing 20% (w/w) gluconic acid from an evaporator has a flow rate of 2000 kg/h and a temperature 90 °C. It needs to be cooled to 6 °C in a heat exchanger with cooling water. The cooling water has a flow rate 2700 kg/h and an initial temperature 2 °C. If the cooling water leaves the heat exchanger at 50 °C, what is the rate of heat loss from gluconic acid solution to the surroundings? Assume the heat capacity of gluconic acid is 0.35 cal/g-°C-1.

The ratio of efficiencies of two filling pipes is 4 : 5. There is a third emptying pipe which efficiency is two third of the average efficiency of first two filling pipes can empty a filled tank in 36 minutes. In how much time both the filling pipes can fill the tank when it is empty?

Are these statements about the aseptic packaging true? Statement 1: It consists of filling and sealing a sterilized packaging material with a sterilized product. Statement 2: High density polyethylene is the most common plastic used for aseptic packaging.

A Carnot heat engine receives heat at 750 K and rejects the waste heat to the environment at 300 K. The net work output of the heat engine is used to drive a Carnot refrigerator, whose COP is 6.14. If the heat removal rate from the refrigerated space is 6.6 kW, determine the rate of heat supply to the heat engine?

The bypass factor, in case of sensible cooling of air, is given by (where td1 = Dry bulb temperature of air entering the cooling coil, td2 = Dry bulb temperature of air leaving the cooling coil and td3 = Dry bulb temperature of the cooling coil)
