3. General information

3.1. DESCRIPTION

In the blender design, it is possible to distinguish three parts or areas that define its build and operation. The top part consists of the hopper, solid-material area, and we can add powder using a butterfly valve with an adjustable handle. Optionally, the butterfly valve can be supplied with a pneumatic actuator. The middle area consists of the venturi, which is the blender's suction, and where the liquid is introduced. The mixing chamber, which is located in the bottom part, is where the liquid meets the powder and produces the mixture. Blender 226 is of a compact design, with the hydraulic part joined to the motor, and clamp-type connections. In the M-440 model, the hydraulic part and the motor are separate and mounted on a baseplate. Transmission is through pulleys mounted beneath the baseplate. The standard motor complies with IEC standards, with IP-55 protection and class F insulation. On request, the motors can be supplied with other protections. All the parts entering into contact with the product are manufactured in AIS 316L. This equipment is suitable for his use in food process.

3.2. OPERATING PRINCIPLE

The blender basically consists of a casing and a centrifugal-pump impeller which are mounted vertically. The suction consists of an annular double-wall pipe that keeps the liquid and powder separate until they enter the mixing chamber. This pipe prevents the powder from becoming damp (see figure 3.1). 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 is introduced tangentially into the impeller blades where the pressure gradient of the blender is zero. 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, firstly, check that the rotating direction of the impeller is correct and then, check that the distribution assembly is correctly assembled. In order to check the distributor installation, draw a continuous arrow from the inlet to the outlet without changing direction (see figure 3.2). During normal operation, a vortex is formed in the centre of the impeller, sucking the powder through the internal venturi and remaining dry. If the vortex is not formed, the powder might become damp and flocs may form in the mixture; the inlet pipe might even become blocked.

Here are the reasons why the powder may become damp or wet:

 Incorrect liquid-intake flow rate A very high flow rate and/or pressure may destroy the blender vortex, and it would

then not be able to pump the liquid with sufficient speed. This can also happen with a very low flow rate, as it causes powder to accumulate on the impeller, thus making it impossible to create the vortex in the centre of the impeller.

 Incorrect pressure. The differential pressure of the blender must be low (6-9 m), the same as the pressure at the

blender intake, which must negative.

Figure 3.1

Figure 3.2

Correct Incorrect

8 3.General information 2014/09

 High viscosity. A viscous product naturally causes counterpressure. Adding this to the counterpressure 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 delivery pressure. If the delivery piping is too long or its diameter is too small, or viscosity is very high, a very high

counterpressure will be caused.

In order to resolve these problems, the piping must be of correct dimensions, or if necessary, a pump must be fitted to the blender outlet. It may be a centrifugal pump, but its pumping capacity is limited if maximum mixture yield is required. If counterpressure increases in the blender, the vortex diminishes thus reducing the mixing capacity of the solid and liquid ingredients. It is also important to maintain negative pressure at the blender intake.

The amount of powder that can be added is very difficult to define, as a great number of variables are involved. Some of these variables are particularly important, such as:

 Dampness  Fatty material content  Microscopic texture (smooth, rough).  Density  Fluidity (air volume in the product)  Powder type (granular, flaky, fines, etc.)

The amount of powder that can be dissolved in the blender depends on the characteristics of the product.

3.3. PRODUCTS TO BE AVOIDED Abrasives: These products deteriorate the mechanical seals and impellers. Effervescents: The gas that these produce prevents the vacuum from forming and the powder from falling from the hopper. High temperatures: It is not advised to work at 65 oC, as vapours may be given off that may cause the venturi to be

blocked. This may also cause cavitation in the blender as it approaches boiling point.

Very high viscosities: The blenders cannot pump highly viscous products. The maximum viscosity of the blenders is 250 cPs. Incompatible products: Products incompatible with the various mechanical seals and elastomers.

3.4. APPLICATION

M-226/440 blenders can be used in any process where powder is added first and is then dissolved in liquid. Examples:

- Powdered milk.

- Whey.

- Chocolates.

- Sauces.

- Brines.

- Fertilisers.

- Lactose.

- Stabilisers, mixtures with milk.

- Pesticides, etc.

Page 10

10 4.Installation 2014/09

4.3. LOCATION

Place the blender as close as possible to the suction tank, and if possible below the fluid level. Place the blender so as to allow sufficient space around it to access the blender and the motor. (See Chapter 8 Technical

Specifications for dimensions and weight).

Set up the blender on a flat, level surface.

Install the blender so as to allow sufficient ventilation. If the blender is installed outdoors, it should be protected by a roof. Its location should enable easy access for any inspection or maintenance operations.

4.4. PIPES

 As a general rule, the suction and delivery pipes should be fitted in straight sections, with the least possible number of

bends and accessories, in order to minimise head loss caused by friction.

 Ensure that blender input and output fittings are properly aligned with the piping and of a similar diameter to the blender

connections.

 Place the blender as close as possible to the suction tank, with the suction nozzle underneath the liquid level to facilitate

priming.

 Place pipe supports as close as possible to the blender’s suction inlet and delivery outlet.

4.5. SHUT-OFF VALVES

The blender can be isolated for maintenance purposes. To this end, shut-off valves should be fitted to the blender's suction and delivery connections. These valves should ALWAYS be open when the blender is operating.

4.6. PRESSURISATION TANK

For models with a dual mechanical seal, a pressurisation tank has to be installed.

Cierre mecánico

1...2m

Figure 4.6: Pressurisation tank installation diagram

For more information on the pressurisation tank (installation, operation, maintenance, etc.), see the manufacturer’s instructions manual.

4.7. ELECTRICAL INSTALLATION

The connection of the electrical motors must be performed by qualified personnel. Take all necessary measures to prevent damage to connections and cables.

The electrical equipment, terminals and components of the control systems may still contain electric current when switched off. Contact with them may be dangerous for operators or cause irreversible damage to the equipment.

Before handling the blender, make sure that the engine is fully disconnected from the power.

 Connect up the motor following the manufacturer’s instructions.

ALWAYS install a pressurisation tank 1 to 2 meters above the connection shaft below the seal. See Figure 4.6.

ALWAYS connect the cooling fluid inlet to the lower connection of the seal chamber. Therefore, the outflow of the cooling liquid will be through the upper connection of the chamber. See Figure 4.6.

7.4.4. Changing belts and pulleys

Loosen the transmission belts (105) by screwing the two tightening screws (25A) in order to facilitate extraction of the belts. Remove the 3 belts (105). Remove the hexagonal screw (52C), washer (35), and pulley (104) from the bearings support side, and the hexagonal screw (52D), washer (35A), pulley stop bushing (17), and pulley (104A) from the motor side. The new fitted belts (105) must be correctly tightened. After a few hours of operation, check that they have not lost their tautness.

Do not tighten the belts too much as this may damage the support and motor bearings.

7.4.5. Changing bearings

Disassembly

First disassemble according to the mechanical seal section and the changing belts and pulleys section. Remove the bearings support group from off the bedplate (38) by removing the hexagonal screws (52) and washers (53). Remove the elastic ring (66A) from beneath the lower bearing (70) using appropriate pliers. Remove the splash-ring (82, 82A). Remove the shaft (05) with the bearings still mounted beneath the support by gently knocking with a plastic hammer on the top of the shaft. Remove the elastic ring (66) and remove the two bearings (70) and separator (17A).

Assembly

Place the top bearing (70) on the shaft (05). Mount the separator (17A) and the second bearing, fixing the assembly with the elastic ring (66). Mount the shaft assembly with the bearings in the support (06) underneath, and fix it with the elastic ring (66A). Place the splash-ring (82, 82A) on the shaft (05). Mount the whole assembly on top of the bedplate (38) with the screws (52) and washers (53).

7.4.6. Changing the motor

(for model M-226) Remove the splash-ring (82, 82A). Loosen the pins (55) and take out the shaft (05) from above. Remove the screws (50A) and take out the motor shroud (14). Remove the hexagonal screws (52) and washers (53) holding the motor (93) at the base of the lantern (04). Hold on to the motor at the same time so that it does not fall. Remove the motor from beneath the feet (07).

(for model M-440) First disassemble according to the belts and pulleys section. Remove the screws (50A) and take out the motor shroud (14). Remove the hexagonal screws (52A, 52B) that are fixing the motor to the bedplate (38) and the tensioner platform (42). Remove the motor (93) with the help of slings due to its substantial weight. At the same time, hold the platform (42) down so that it does not lift with the motor.
