composting process | production steps | types | features

The composting process is usually divided into two stages, one is compost material fermenting(also called fast or high temperature fermentation) and the second is compost further treatment (also called post-ripening or aging). There is usually no clear boundary and distinction between these two phases.

The characteristics of a composting phase are: high oxygen absorption rate, high temperature, large reduction in degradable volatile solids (BVS), and high odor potential. Typically, a composting phase requires ventilation and maintains good control of the composting process due to the need to reduce odor. The secondary composting stage is characterized by low temperature, low oxygen absorption rate and low odor potential.

Compared with the first composting, the management and regulation of the secondary composting stage is relatively simple. However, from the engineering point of view, there is no need for secondary composting, because the secondary composting stage can continue to degrade the organic matter that is difficult to degrade, and the reaction rate is slowed down. And reconstitute low temperature microbial communities to help compost maturity, reduce phytotoxic substances and inhibit pathogens. These two phases are indispensable for the design and operation of a complete composting system and are necessary for the production of composted compost.

The raw material processing before the start of one composting is called pre-treatment, and the raw material processing after the post-cooking stage is called post-treatment. Whether the pre-treatment or post-treatment needs to depend on the characteristics of the raw materials and the desired product quality.

The warming phase generally refers to the initial stage of the composting process, in which the temperature of the stack gradually rises from the ambient temperature to about 45 C, the dominant microorganisms are mesophilic microorganisms, including bacteria, fungi and actinomycetes. The decomposition substrates are mainly sugars and starches. During the period, fungal fruiting bodies can be found, and animals and protozoa participate in decomposition.

When the temperature in the high temperature stage rises above 45 C, it enters the high temperature stage. At this stage, the mesophilic microorganisms are inhibited. The system even died, while thermophilic microorganisms rose to dominant microorganisms. Residual and newly formed soluble organic matter in compost continues to be oxidatively decomposed, and complex organic matter such as hemicellulose-cellulose and protein are also beginning to be strongly decomposed. Microbial activity alternates. The most active ones are thermophilic fungi and actinomycetes at around 50 C. When the temperature rises to 60 C, the fungus almost completely ceases to function. Only thermophilic bacteria and actinomycetes are active. Most of the thermophilic microorganisms are no longer adapted to 70 C and enter the dormant and death stages in large numbers. The optimum temperature for modern compost production is typically 55 C, because most microorganisms are most active in this temperature range, most decomposing organic matter, and most of the pathogens and parasites can be killed.

The high temperature stage in the cooling stage will inevitably lead to the death and activity of microorganisms, and naturally enter the low temperature stage. At this stage, the mesophilic microorganisms began to take the lead, further decomposing the organic matter that is difficult to decompose, but the microbial activity generally decreased, the heat generation of the heap decreased, the temperature began to decrease, the organic matter stabilized, and the oxygen demand was greatly increased.

open mouth bagging machine for wood pellets [model gwb] - choice bagging equipment

open mouth bagging machine for wood pellets [model gwb] - choice bagging equipment

A producer of wood stoves in New York was seeking an open mouth bagging machineto package 3,000 pounds of wood pellets into 40 pound plastic bags to match the production rate of their pellet milling process. They wanted a system that would be fast, weight accurate and economical. Additionally, the only available electrical power at the facility was single phase so all equipment had to be designed to operate on 220 volts single phase.

To achieve the clients objectives, Choice Bagging Equipment recommended a system featuring a Model GWB open mouth bagger and an in-line band sealer system. Product was fed to the bagging machine by an overhead supply hopper that held approximately 1,500 pounds of material. The system required two operators. One operator places empty bags on the filling machine and guides them through the sealer machine. The second operator palletizes the filled bags at the end of the line.

The Model GWB bagging machine featured an integrated digital weighing scale that started at the press of a foot pedal by the system operator. It stops and releases from the filler once the target weight had been achieved. Filled bags were automatically discharged onto a specially designed bag closing conveyor and transferred to and through a continuous band sealer that provided 100% positive bag closure. A sealer integrated bag trimmer provided a uniform look to the sealed end of each bag. Sealed bags were elevated to waist high on a powered belt conveyor and palletized by a second system operator at the end of the packaging line.

Each filling sequence was semi-automatic meaning that an operator would manually hang each bag, depress a foot pedal and then it would be filled to a pre-programmed weight, stop filling and release automatically. The filling machine had an integrated weighing scale, which worked in combination with a single PLC based control package. The weighing controls were especially designed for valve bag filling applications and featured a gain-in-weight totalizing display. The controls were designed with the ability to communicate weigh data to a printer or central management control system.

The flow of material was automatically started and stopped by a variable 3-position gate valve (called a gravity gate). The integrated digital control and weighing system would signal the pneumatic functions of the machine on and off in the correct sequence including the pneumatic gate valve would regulate the amount of material into the bag.

Often customers come to us with a specific bag filling machine in mind, but after a few minutes of conversation with us about what they want to accomplish in their production line, a different bagging machine is recommended, often a less costly solution. This post will describe the three basic types of industrial and agricultural []

Its not surprising that pressure is an important factor in bagging dry bulk powders; for a cement bagging machine or concrete bagging machine it is especially critical to speedand weight accuracy. This article explains how one customer significantly improved productivity and accuracy by following the fundamentals. Our Model 730 Pressure Flow Air Packer is one []
