INFRARED ADVANTAGES

• Infrared offers cycle times 50% to 70% shorter than convection heating.
• Infrared heating is highly efficient because the process heats only the product, not the surrounding air. Infrared energy is not absorbed by air and does not produce heat until an object absorbs it.
• Infrared offers higher heating rates, which means faster production using less floor space
• Electric infrared is an enviornmentally friendly process, with no ozone depleting or green house gases released. Powder coatings and water based paints are ideally suited for infrared, elemeting solvent based processes.
• Heated times for infrared emittersis minimal, reducing energy costs. The equipment can be turned on minutes before production begins and turned off during breaks and lunch periods.
• Infrared ovens require less maintenance. They have few, if abny, moving parts
• On the average, electric infrared ovens are 3 times more efficient in delivering energy to the product than gas convection ovens.
• With todays infrared technology, complex shaped objects can be cured, as well as flat shapes.
• Infrared can provide very high temperatures at a much lower cost than convection systems. Infrared is used to achieve product temperatures above 12000F.
• Infrared is the clean, quiet, worker friendly choice.
• Adding a short infrared oven section in front of a convection oven can offer increased production with a minimal capital investment.

COMPARING DIFFERENT FORMS OF INFRARED HEAT :

Through the years many different forms of infrared heat sources have been developed. Some of the more familiar forms seen today are metal sheathed tubular heaters, quartz tubes, quartz lamps, gas fire catalytic, flat face panels and ceramic heaters

A thermostat controls temperature at any point from 50C above ambient 950C. The accuracy of control is + 10C upto a temperature of 600C and + 20C at a higher temperature and is provided with a pilot lamp. The heating element and the thermostat stem are protected by a perforated false bottom.

Standard Walk-In Ovens include a steel plate floor and provisions for a custom installed insulated floor. Floor plate is " thick in ovens up to 72" wide x 120" long; thick on wider models. A doorsill at the front edge of the floor plate maintains doorway rigidity and provides sealing surface for the oven doors. The doorsill is 2" high on 2750C and 3500C ovens; 3" high 4000C ovens.

At no charge, the doorsill can be eliminated, door lengthened and equipped with drag seals. This arrangement provides a floor level entrance to allow loading by hand truck, fork lift truck or by loading equipment to varying wheel spacing.

When loading with an over truck, installation of truck wheel guide is recommended. This allows the doorsill to remain across the work space opning. Floor level truck wheel guide track openings beneath the doors.

Truck wheel guide track width and centerlines may be specified to suit existing equipment or to be used with a loading track from the front of this bulletin. Guide tracks are generally wider than track wheel width. If not specified, tracks are provided 2 wide on centerlines 12" less than work space width.

• The instrument can also be mounted on Tabletting machine.
• Easy to install and operate
• Tests tablets upto 25 mm diameter
• Dial calibrated for 0-20 kgf with a least count of 0.2 kgf

Load is applied by hand to a lever transmitting pressure from the tablet to be crushed, through a compression load spring registering the force onto a calibrated dial gauge. This dial gauge is provided with a "Main" as well as a "Follower" reading hands. As the level is pressed, both hands move in tandem. And, once the tablet is broken, the main hand comes back to zero position, while the follower hand remains locked at the reading to denote the breaking force. This facilitates accurate recording of the reading.

he crushing of a tablet results in tablet splinters flying in all directions. To prevent this, an acrylic guard surrounding the tablet-crushing chamber is provided. The splinters are thus restricted to the chamber. After the test is over, the acrylic guard can be swiveled and the splinters removed with the help of a brush.Tablet hardness tester is supplied in elegant wooden box with Stand, Adapter for validation, Allen Key and cleaning brush.

Sakav is a commercial quality bin dryer used to dry products requiring long dwell times. The advanced design of Sakav Bin Dryers maximizes production and minimizes down time, by affording discreet control over the process air temperature, air velocity, and humidity, not as a group, but to each individual bin. The results are spectacular, often five bins do the work of eight standard units. Dehydration is virtually continuous, with three bins running, while the fourth bin is filling, and the fifth bin is discharging dried product

• Wet product enters at top of dryer and exits at bottom.
• Hot, dry air enters at bottom of dryer, recirculates through various decks (reheated as necessary), and exits at top.
• This means that driest product contacts driest air, and wettest air contacts wettest product, which is most efficient airflow.

• Each deck retains product for a timed interval, then gravity transfers, or cascades product to deck below as a batch.
• This process repeats until products pass completely through dryer in a very controlled manner.
• Product decks incorporate a simple, pivoting tray design, operated by hydraulic cylinder. Trays pivot 90, dumping entire product bed instantly.
• Decks are dumped in sequence, starting at bottom. This means that each deck is empty and closed before next product falls onto it, thus assuring product separation.
• Top (accumulation) deck includes a suitable product spreader to ensure a uniform bed depth. One version features a rotating spout and rake spreader that levels bed. Other versions are available.
• Rotary airlock at product inlet to compensate for negative air pressure.
• All decks will have same bed depth and retention time, except for top one. Bed depth and retention time for top (accumulation) deck will vary, since it is continuously filling.
• A minimum of five dryer decks (one accumulation, and two temperature zones) is required to ensure minimum moisture variation

• Air direction alternates up and down between decks.
• A temperature zone consists of two decks. There are two recirculation fans and one heating system per zone. The upper deck of the pair has the fans. The lower deck has the heating system.
• Recirculated air works its way up dryer zones, using settling chamber as an interconnection duct, and is exhausted at top. This means that each zone recirculates only as much air as required, and is independent of other zones.
• Recirculated air enters through ducts on both sides. These ducts feature splitter vanes to improve uniformity of airflow.
• Recirculated air on both sides of back plenum passes through dampers (optionally motorized). This permits regulation of air velocity through product.
• Internal ducting maintains high air velocity, keeping any fines in suspension. As air passes through settling chamber, air velocity is reduced significantly, causing any fines to fall out of suspension. Fines fall to bottom of settling chamber, where a single fines auger removes them.
• Baffles in settling chamber prevent falling fines from zones above being drawn into recirculation ducts of lower zones.
• Top (accumulation) deck has small quantity of ambient air drawn down through it to eliminate possible condensation, without significant drying of product. Drying on this deck is minimized because retention time varies on this deck as it fills.
• If integral cooler is included, cooler air is then used as dryer makeup air to increase efficiency. If not, outside air or air from separate cooler is added to bottom zone.
• If more than one cooler deck is used, cooler air flows through all cooler decks, from bottom to top. This minimizes cooler air, thus not exceeding dryer requirement for makeup air. When necessary, excess cooler air can be exhausted directly.
• Each zone can have its own temperature and air velocity, independent of other zones

• Dryers may be gas fired or steam heated. Other heat sources are possible.
• Fans and burners (or steamcoils) are housed in insulated back plenum

• Dryer is designed to support catwalks all around dryer at each zone.
• Hinged access door on front of each deck provides easy access to product area.
• Thermal insulated window on each deck permits visual inspection of product during drying.
• Hinged side doors provide full access to side ducts for maintenance.
• Hinged doors on back side permit access inside internal ducting and fines settling chamber for maintenance.
• Space around internal ducting inside back plenum is accessible through doors for maintenance. Grated platform and access ladder is included inside each zone. This space is accessible during operation.
• Removable panels permit access to fan wheels. Fan drives and bearings are mounted externally.
• Heating system valves and controls are located outside of dryer for easy maintenance.

• Dryer/Cooler is PLC controlled. Complete computer control is available as an option, tying it into extruder controls. Feed forward moisture control is also an option.
• Hydraulic cylinders that operate dump mechanism on each deck control tray dump cycling. These are controlled by PLC timers that switch solenoid valves connected to cylinders.
• Bed depth level sensors are included on top (accumulation) deck to alarm if bed depth and retention times are not synchronized.
• Rake spreader features remote controlled lifting device with position transducers, to precisely control bed depth from PLC as an option.
• Temperature zones consist of two decks. Each zone includes RTD temperature sensor and PID type controller that adjusts valve in gas or steam line for that zone.
• Pressure transducers measure pressure drop through each bed. Additional devices measure air velocity in each zone. This is used to control air velocity through product.
• Fittings are included for installation of additional RTDs at each deck and in exhaust air for additional temperature monitoring if required.
