Designing of the dryer section of nutritional yeast production plant – Industrial sector review – Part 20 Spray-air contact Mixing and flow is an important factor in the design of spray drier. The product and air flow into the dryer can be designed in co-current, counter-current or mixed flow patterns. Sine heat sensitive product is […]
Designing of the dryer section of nutritional yeast production plant – Industrial sector review – Part 18 Feed cream is introduced centrally on to a wheel rotating at speed of 10 000 r.p.m. The feed flows outwards over the surface, accelerating to the outer boundary of the atomizer. The cream on leaving the atomizer readily […]
Designing of the dryer section of nutritional yeast production plant – Industrial sector review – Part 17 Atomization of feed It is necessary to dispense and distribute the cream under control conditions, which is done by the atomizer. Generally the atomizers are divided into two sub division, namely (1) Rotary and (2) Nozzle atomizers. The […]
Designing of the dryer section of nutritional yeast production plant – Industrial sector review – Part 16 PROCESS DESCRIPTION In this section, details of the mass and energy balances along with the drying process description are detailed. Introduction Yeast broth from the fermentor is delivered to separator which produces a thick suspension of yeast (cream). […]
Designing of the dryer section of nutritional yeast production plant – Industrial sector review – Part 15 For the cycle of the air, please see attached Psychometric charts Saturated Wet bulb temperature of the Air = 55 °C (after heating to 300 °C) Drying Air Mass flow rate = 20,685 kg/hr Drying Air Volumetric Flow […]
Designing of the dryer section of nutritional yeast production plant – Industrial sector review – Part 14 Using this efficiency, the total product loss is calculated as 0.06 x 348.5 = 2.091 k/hr, which equals 16560 kg/year (plant running for 330 days). The product is sold at £10/kg, which also includes further processing costs which […]
