3. Safety

Safety hazard for people in general and/or for the equipment

ATTENTION Important instruction to prevent damage to the equipment and/or its function

3.2. GENERAL SAFETY INSTRUCTIONS

Read the instruction manual carefully before installing and starting the blender. Contact

INOXPA in case of doubt.

3.2.1. During installation

Always take into account the Technical Specications of chapter 9.

Never start the blender before connecting it to the lines.

Do not start up the blender if the cover has been removed and the impeller is xed to the

blender.

Check for proper specications of the motors, especially if working conditions create an

explosions hazard.

3.2.2. During operation

The Technical Specications of chapter 9 should always be observed.

Under no circumstances can the specied limit values be exceeded.

NEVER touch the blender or the pipework during operation if the blender is being used

for transferring hot liquids or during cleaning.

The blender contains moving parts. Never place your ngers inside the blender during

operation.

NEVER operate with the suction and discharge valves closed.

NEVER spray water directly on the electrical motor. The standard motor protection is

IP55: protection against dust and water spray.

Electric hazard

During the installation, all the electric work should be carried out by authorized personnel.

3.2.3. During maintenance

The Technical Specications of chapter 9 shall always be observed.

NEVER disassemble the blender until the pipes have been emptied. Remember that

liquid will remain inside the housing (if does not have a purge). Bear in mind that the

product may be hazardous or extremely hot. Consult the regulations in e󰀨ect in each

country for these cases.

Do not leave loose parts on the oor.

ALWAYS disconnect the electrical power to the blender prior to carrying out any mainte-

nance.

Remove the fuses and disconnect the cable from the motor’s terminals.

All electrical work must be carried out by authorized personnel.

4. General Information

4.1. DESCRIPTION

4.2. OPERATING PRINCIPLE

A blender consists, basically, of a casing and a centrifugal pump impeller which are mounted verti-

cally. The following three parts can be distinguished:

- the hopper, located at the top, is the solid material area, which is added using a buttery valve

with regulable handle or with pneumatic drive.

- the middle area consists of the venturi, which is the blender’s suction and where the liquid is

introduced.

- the mixing chamber, located at the bottom, is where the liquid and solid material are meet and

the mix is produced.

The M-226 blender has a compact design, the hydraulic part is joined to the motor and the connec-

tions are clamp type.

The M-440 blender has the hydraulic part and motor separated and they are mounted on a baseplate.

The transmission is through pulleys mounted beneath the baseplate.

All the parts in contact with the product are manufactured in 1.4404 (AISI 316L) stainless steel.

The standard motor complies with IEC standards, with IP-55 protection and class F insulation.

The internal venturi, where the aspiration of the uid is produced, has an annular double-wall pipe,

as shown in gure 02.002.32.0006, that keeps the liquid and powder separate until they enter the

mixing chamber. This pipe prevents the powder from becoming damp.

The suction created by the blender impeller sucks the powder from the hopper through the internal

venturi to the mixing chamber. The other pipe is used to introduce the liquid towards the impeller. The

liquid enters the mixing chamber tangentially, following the same rotating direction as the impeller. In

this way, the powder-inlet pipe remains dry while the blender is in operation.

If the inlet pipe appears to be blocked, check that the rotating direction of the impeller is correct and/

or that the distribution assembly is correctly assembled.

To check the distributor installation, draw a continuous arrow from the inlet to the outlet without chan-

ging direction as shown in gure 02.002.32.0007. During normal operation, a vortex is formed in the

centre of the impeller, sucking the powder through the internal venturi. If the vortex is not formed, as

shown in gure 02.002.32.0008, the powder might become damp and ocs may form in the mixture;

the inlet pipe might even become blocked.

General Information

The M-226 and M-440 blenders are suitable for his use in food process. They can be used in any

process which needs to mix solids and liquids as powdered milk, whey, chocolates, sauces, brines,

fertilisers, lactose, stabilisers, etc.

4.3. PRODUCTS TO BE AVOIDED

4.4. APPLICATION

The products to be avoided in order to have a blender optimum operation are:

-abrasives: these products deteriorate the mechanical seals and impellers.

-e󰀨ervescent: The gas that emits these products prevents the vacuum from forming and the

powder from falling from the hopper.

-high temperatures: it is not advised to work at temperatures above 65 oC. At higher temperatu-

re a product vapours may be given o󰀨 that may cause the venturi to be blocked. This may also

cause cavitation in the blender as the temperature approaches the boiling point.

-very high viscosities: the blenders cannot pump products with a viscosity above 250 cPs.

-incompatible products: products incompatible with the various mechanical seals and

elastomers.

Other reasons why the powder may become damp or wet:

-incorrect liquid-intake ow rate: A very high ow rate and/or pressure may destroy the blen-

der vortex, and it would then not be able to pump the liquid with su󰀩cient speed. This can also

happen with a very low ow rate, as it causes the powder to accumulate on the impeller, thus

making it impossible to create the vortex in the centre of the impeller.

-incorrect pressure: the di󰀨erential pressure of the blender must be low (6-9 m), the same as

the pressure at the blender intake which must negative.

-high viscosity: a viscous product naturally causes counterpressure. Adding this to the coun-

terpressure caused by the grille leads to very high pressure. It is advisable to remove the grille,

which is an optional part when highly viscous products need to be mixed.

-high discharge pressure: if the discharge pipe is too long or its diameter is too small, or visco-

sity is very high, a very high counterpressure will be caused.

If counterpressure increases in the blender, the vortex diminishes thus reducing the mixing capacity

of the solid and liquid ingredients. To resolve these problems the piping must be of correct dimen-

sions, or if necessary, a pump must be tted to the blender outlet. It may be a centrifugal pump, but

its pumping capacity is limited if the maximum mixture yield is required. it is also important to main-

tain negative pressure at the blender intake.

The amount of powder that can be added is very di󰀩cult to dene, as a great number of variables are

involved like dampness, fatty material content, microscopic texture (smooth, rough), density, uidity

(air volume in the product), powder type (granular, aky, nes), etc.

5.3. TRANSPORT AND STORAGE

The blenders are often too heavy to be stored manually.

Use an appropriate means of transport.

Use the points which are indicated in the drawing for lifting the blender.

Only authorized personnel should transport the blender.

Do not work or walk under the heavy loads.

Lift the blender as indicated below:

- always use two support points placed as far apart as possible.

- secure the supports so that they will not move.

See chapter 9. Technical Specications to consult the dimensions and weight of the blender.

During the transport, disassembly or assembly of the blender, there is a risk of loss of

stability and that the blender could fall down and cause damages to the operators. Make

sure that the blender is properly supported.

5.4. LOCATION

Place the blender as close as possible to the suction tank whenever possible below the liquid and

leaving enough space around to can access the blender and the motor. If necessary, consult in chap-

ter 9. Installation the dimensions of the blender.

Once a place is chosen, the blender should be mounted on a at and level surface.

Install the blender so as to allow proper ventilation.

If the blender is installed outdoors, it should be covered by a roof. Its location should

allow easy access for inspection or maintenance operations.

5.4.1. Excessive temperatures

Depending on the uid to be mixed, high temperatures can be reached inside and around the blender.
