BELT DRIER

 

FOR BIOMASS AND WASTE

 

 

the Perry Belt Drier is ideally suited to drying almost any non-flowing product or more granular products that require a lower throughput capacity. Popular applications have included biomass, anaerobic digestate, grass & seeds. 

The Perry Belt Drier is ideally suited for these materials:

Wood chip - Wood shavings - Wood pellets - Other feed pellets - Saw dust - Biomass straw - Miscanthus and bagasse - Herbs - Combinable crops - Beans and soya beans - Shredded recycled matter - Sewerage sludge & digestate - Flaked maize - Nuts - Fruit and fruit slices - Compost - Cotton rejects - Extruded pet foods - Finely ground wet chips - Grass - Grass seed - Orange peel - Pulp granulates - Solid shredded waste - Granular & shredded plastic - Poultry manure

Traditionally drying these types of materials has been achieved by rotary drum driers, however this method has many disadvantages, including:

The Perry belt drier overcomes all of the issues listed above, along with being more economically efficient due to the lower operating temperature and providing the opportunity to recover waste heat.

Belt Drier Principle of Operation

 

Drying for Biomass:

 

It’s highly likely that your biomass materials need to have their water content reduced before you can use them, to:


 

Key Points

 


 

General Design

 

Modular galvanised steel construction available in 1.5m, 2.2m and 3m widths. The drier can be increased in length in 1m increments from 8.5m to 38.5m (including drive and tail). The overal height of the drier is dependant on the heat source chosen.


 

Heat Sources Available

 

HEAT EXCHANGERS


These are commonly used for application where a biomass heat source is available such as woodchip boilers to produce hot water or if there is a steam heat source available.
The drier can be tailored to accept a customer’s existing heat exchangers if required.

 

OIL OR GAS FIRED BURNERS


If a separate heat source is required a direct fired furnace with diesel, kerosene, LPG or natural gas burner can be used. Alternatively a heat exchanger with the same burner can be used for indirect heating if required.

Overview

 


 

Control Panel App

 

We are pleased to announce the launch of an app and remote desktop connection which allows you to connect to and control your Perry PLC control panel from any PC or IOS / Android mobile device.*

The app allows users more flexibilty when operating their driers; you can now operate the panel or check the status of your Perry equipment from wherever you happen to be.

 

Full control of your drier from anywhere with a WiFi or 3G/4G connection!


Phone Application

 

Free app available from both Apple App store and Google Play Store.

Remote Connection

The remote desktop allows more in-depth analysis of your control panel. Status reports and alarm history have never been so easy to access.

Sit at your computer while keeping a close eye on your drier!

 


 


Remote Desktop Operation

 

Your panel is connected to the internet which allows you to access the following within your drier panel

 

*Panel must be connected to the internet with a static IP address and port forwarding facility, no app currently availablefor Windows devices.


 

Perry Belt Drier Key Points

Fitted with a universal belt, the Perry Belt drier is suitable for all granular products, woodchip, shavings, sawdust, paper pulp, grass, herbs, vegetable slices, SRF, RDF, silica granules, clay pellets and grain. The belt is tightyly woven, so very few product fines will pass through.

 

The air enters the top of the drier and is drawn through the product and the belt. This makes our drier ideally suited for drying light crops as they are not blown off the bed by the air flow; they are consolidated onto it. This means more air gets through the product and allows for maximum drying efficiency. It is particularly good for sawdust, herbs and grasses.

 

The Perry belt drier does not have chains or slats, keeping it very clean. In driers with slats and chains, when products such as grass or herbs are being dried the residue left will decompose and the bacterial count inside the drier will increase. In the Perry belt drier there is less chance of damage as materials cannot get stuck in the slats and chains. As the product is fed onto the belt and is stationary during the drying process the Perry belt drier is very gentle to the product; there will be no damage caused by it being dragged through the drier over a metal bed by chains and slats.

 

Slow moving, and very few moving parts, so rates of wear are very slow and cheap to maintain.

Galvanised modular construction. 2m long standard sections. Drive, tail and tensioning section are sent to site pre built. The rest of the sections are sent to site in panel form. The drier can be extended after purchase at a later date very easily. This makes it easier to plan for the future and extend the drier instead of having to add another. Also, the galvanised construction is well suited to resisting corrosion caused by the damp air when drying.

 

Becasue there is no louvre system or mesh material that the product is being moved over there are no air gaps to become clogged by small residue, so the drier performance stays consistent and there is no perforations to clean in the drier body.

There is a rotary brush to clean the belt as standard and for usual biomass and granular products this should be satisfactory. Every piece of belt is cleaned once per revolution automatically.

Alternative cleaning methods include an air knife, which can blow small particles out of the belt, or a high pressure water jet cleaning system for more sticky products. Both methods work after the drive drum to clean the belt before returning to the inlet.

The PLC screen is full colour. There is an SD card in the PLC and it logs data to this, which can then be plugged into a laptop and downloaded or if there is an internet connection with a fixed IP address you can connect remotely and download it. We can also connect from the office to the drier for diagnostic purposes. The internet connection allows remote control and monitoring of the drier for diagnostic purposes. The internet connection allows remote control and monitoring of the drier using a laptop or mobile device.

 

 Automatic control as standard is by measuring air temperature on the same principle as the grain drier. The way this works is to measure the air temperature above and below the belt at the inlet and outlet of the drier. When the temperature below the belt drops at the inlet this indicates damper chip entering the drier; the PLC will then slow the belt down to compensate. If the temperature below the belt at the outlet end increases this will indicate that the chip is getting over dried so the PLC will speed the belt back up a little. An extra cost alternative will be a system using microwave sensors to actually measure the moisture and control the speed from these readings. With the moisture sensors the actual moisture is measured but the PLC program makes the adjustments in the same way.

Sealing for product leakage and air leakage is done using a soft rubber side skirt. This is adjustable as it wears to help maintain and efficient seal, they are a slow wearing part.

 

We have an automatic belt tracking device which works using a sensor at the side of the belt to sense if the belt wanders to one side. If the sensor is touched an electric actuator changes the angle of the tracking roller which sends the belt across to the opposite side.

 

For large scale applications enclosing the drier in a Kingspan composite panel structure is a good alternative. This means the main galvanised body is completely covered by the insulated panels, apart from the drive and tail end of the drier. The HEX can easily be mounted on the vertical side of the structure and the fans can be either mounted on the roof or top of the vertical side of the cold plenum. The drier can be made to blend in with its surroundings. It is more expensive than standard galvanised finish,
