T a s k T h r e e . Read and sum up the main facts of the text.
Food processing and food production on the farm are closely linked. In an
article on 'Dairy farming in a new environment' Ian McCluggage from the Col-
lege of Agriculture, Food and Rural Enterprise explores the farm business chal-
lenges farmers must meet if they are to be successful.
A forum to discuss matters relating to the content of the Dairy Science and
Food Technology site is provided. At the 13 December 2008, 114 topic areas
and 516 messages including: lactose intolerance, slits/cracks in cheese, deaths
from a probiotics trial in the Netherlands, patent applications, standardizing
milk for cheese manufacture, the control of bitterness in Gouda cheese, salt
reduction in cheese, benzene in soft drinks, making Coulommiers cheese from
goats' milk, and cheese yield were recorded. There is also a searchable data-
base of literature cited in the website.
T a s k F o u r . Use the verbs in brackets in the correct form.
Washing solution (send) to the circuit by centrifugal pumps. To optimize
the washing process pumps output (regulate) by frequency converter. Con-
sumption (regulate) automatically by control system.
Washing solutions (heat) by a plate heat exchanger. Steam with overpres-
sure up to 4 bar acts as a heating agent. Heating (do) during circulation along
the lesser circuit "tank – pump – heat exchanger – tank". Station can (equip)
with heat regeneration system if necessary.
The set temperature of washing solution automatically (keep) by the con-
trol system during washing.
Transferring return washing stream to the corresponding tank and rinse
water to outlet (do) automatically, while the washing program is running after
the signal of a sensor installed in the return line.
Mixing washing solution is done during solution circulation along the
lesser circuit. Dozing is done to the specified conductivity of the washing solu-
tion. After that the dozing pump (turn) off. Process is done automatically while
the washing preparation program is (run) and (control) by the control system.
Each tank with washing solution is equipped with level sensors.
To doze concentrated washing solutions in the tank the station (equip)
with two dozing stations for preparing concentrated caustic (up to 50%) and
concentrated nitric acid (up to 65%).
Water input to the fresh water tank is done automatically while the washing
program is running.
Caustic tank and acid tank (fill) with water automatically while the washing
preparation program is running and is controlled by control system. Tanks can
be filled manually as well.
