Types of Vinasse Dewatering Decanter Centrifuges

A vinasse dewatering decanter centrifuge is a type of mechanical equipment that separates solid particles from liquid fluid by utilizing centrifugal force. This apparatus is extensively used for dewatering or drying up the liquid that is usually referred to as vinasse or stillage in the liquor or ethanol production industry. The working of a vinasse dewatering decanter centrifuge can be demonstrated in three distinct steps: the feed, separation, and discharge.

Alkali, acid, or polymer-based flocculation are used to treat the feed, which is then pumped into the centrifuge at a no-load angle. In the separation phase, the solids and liquid separate as the centrifuge rotates, with solids settling on the cone's wall. During the discharge stage, the settled solids are scraped off while the centrifuge is still in motion, and the liquid that comprises the unsettled solids is released from the central part of the cone.

This industrial machine plays a vital role in managing vinasse efficiently and extracting valuable by-products from the process. The decanter centrifuge not only dewaters vinasse but also reduces its volume significantly, making it more manageable for further treatment or disposal.

There are several types and models of cafeteira centrifugas de vinasse disponíveis to cater to varying industrial requirements. These can be differentiated based on their operating techniques, how the separation happens, production capacity, size, and other criteria.

• Based on operation technique: There are automatic and semi-automatic kinds of vinasse decanter centrifuges, where the former operates on its own without needing assistance because of the feeding pump and automatic control panel, and the latter requires manual involvement for sampling and adjusting the quantity of chemicals added.
• Based on how separation happens: The continuous separation function of a vinasse decanter centrifuge lets it operate for extended periods, whereas the batch separation kind makes it work for a limited time and then stop to discharge the separated components.
• Based on the size of the apparatus: There could be small, medium, large, and oversized machines, but in most cases, only a non-stopping feature is available for the bigger types of equipment, such as the open type, which can be serviceable from either side, while others are available for the centrifuge to be serviced from just one side.
• Based on the capacity of separation: Liquid-solid separation centrifugals, like a vinasse decanter centrifuge, fall under different models because of their settled area, whose sizes are bigger compared to smaller centrifugals which are regarded as gravitational.

Specifications and Maintenance

Specifications

The main specifications to pay attention to when buying a vinasse dewatering centrifuge include the machine's length and diameter.

• Length and diameter: The longer and wider a centrifuge is, the higher its capacity for processing vinasse will be. For instance, there may be centrifuge models available that are as long as 3 meters and have a diameter of around 300 mm. Such large-decanter-centrifuges could be expected to process over 10,000 liters of liquid per hour.
• Motor power: The motor power of vinasse decanter centrifuge will vary depending on its length and diameter. In general, a larger centrifuge will have higher motor power. Some available models have about 45 to 120 kW of motor power. Higher motor power will result in greater processing capacity.
• Weight: The weight of the centrifuge may also increase with its dimensions and motor power. A longer and wider centrifuge could weigh around 8,000 kg. The heavier weight may require the use of a pump to discharge solid residue from the centrifuge.

Some suppliers may be able to provide a complete datasheet that lists all specifications of the available vinasse centrifuge models.

Maintenance

• Cleansing: Perform periodic cleaning of the unit to prevent the buildup of deposits and impurities inside the equipment. For that, use the cleaning agent recommended by the manufacturer and follow the established procedures. Ensure that the apparatus is disconnected from the electrical and water supply prior to cleaning.
• Check for leaks: Frequently check for possible leaks in the equipment, such as in connection points and hydraulic circuits. In the event of identifying any leakage, promptly correct the defects to avoid waste and damages to the equipment.
• Adjustments: Periodically check and adjust the centrifuge's belt drives. Ensure that they are properly tensioned and aligned, minimizing the risk of premature wear and breakdowns. Also,, adjust the inlet flow control valve, ensuring that the centrifuge is fed with an appropriate and constant volume.
• Lubrication: Centrifuge bearings and transmission components must be lubricated according to the manufacturer's recommendations. This operation is essential for ensuring smooth functioning, reducing wear, and extending the service life of the equipment.

Application Scenarios for Vinasse Dewatering Decanter Centrifuges

The proper management of distillery wastewater or vinasse through effective dewatering is crucial for minimizing environmental effects and maximizing asset use. Vinasse dewatering decanter centrifuge serves several industries, including agriculture, waste management, distilleries and breweries, and energy production, as follows:

• Distilleries and Breweries: Vinasse Decanter centrifuges are primarily designed for handling vinasse from distilleries and breweries.
