4. General Information
4.1. DESCRIPTION
4.2. OPERATING PRINCIPLE
The MH blender is a compact unit. It consists of a centrifugal pump with a venturi system and a ho-
pper above which there is a hopper with a buttery valve. The solids are added through the hopper
to the pumper liquid.
The pump is in the Hyginox SE range. This pump is a close-coupled centrifugal pump with a hygienic
and horizontal design and a single-stage. It is has a circular casing with axial suction and a tangential
discharge. The main pump components are pump casing, impeller, cover, lantern and a shaft that is
rigidly coupled to the motor shaft. The standard IEC motor of type is protected by a stainless steel
shroud.
The aspiration of the pump creates a suction that aspirated the solids of the hopper in a way that
the solids are incorporated into the liquid. Continuedly, the ow passes through the centrifugal pump
where the premix of the solid is created.
The inlet of solids is regulated by a buttery valve on the basis hopper. The tube in which the inlet of
the pump is produced remains dry during the blender operation. If the inlet tube is plugged, check
that the pump direction of rotation is correct and check the ow is su󰀩cient.
The reasons why the powder may become damp or wet are:
-incorrect liquid-intake ow rate: with a little ow, normally created by back pressure on the
discharge of the blender too high, is possible that the ow is not being able to drag the solids
which enter from the hopper and, even they rise through the tube to the hopper.
-incorrect pressure: the di󰀨erential pressure of the blender must be low (6-9 m), and the pres-
sure at the blender intake must be negative but without causing cavitation because it is counter-
productive.
-high viscosity: due to its nature, a viscous product will cause counterpressure. This can cause
the blender to move an inadequate ow to its correct functioning. A centrifugal pump dramatically
reduces its ow if the product viscosity increase.
-high discharge pressure: if the discharge pipe is too long or its diameter is too small a very
high counterpressure will be caused.
To avoid these problems the piping must be of correct dimensions. It is important to maintain nega-
tive 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, powder type (granular, aky, ne), etc.
The MH blenders are suitable for his use in food processing. They can be used in any process which
needs to mix solids and liquids suchs 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 65⁰C. Also, if the tempera-
ture approaches the boiling point can cause cavitation in the blender.
-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.

8.6. CLEANING
The use of aggressive cleaning products such as caustic soda and nitric acid may give
raise to skin burns.
Use rubber gloves during cleaning procedures.
Always use protective goggles.
8.6.1. Automatic CIP (clean-in-place)
If the blender is installed in a system with a CIP process, it is not necessary to disassemble the
blender.
If the automatic cleaning process is not provided, proceed to disassemble the blender as indicated
in the chapter 8.7. Disassembly and assembly of the blender.
ATTENTION
Check the concentration of the cleaning solutions. Incorrect concentrations may lead to
the deterioration of the blender seals.
To remove any traces of cleaning products ALWAYS perform a nal rinse with clean water at the end
of the cleaning process.
Two types of solutions can be used for CIP processes:
a. alkaline solution: 1% by weight of caustic soda NaOH a 70ºC (150ºF). To make this solution:
1 kg NaOH + 100 l H2O1= cleaning solution
2,2 l NaOH 33% + 100 l H2O = cleaning solution
b. acid solution: 0,5% by weight of nitric acid HNO3 a 70ºC (150ºF). To make this solution:
0,7 l HNO353% + 100 l H2O = cleaning solution
1) only use chlorine-free water to mix with the cleaning agents
8.6.2. Automatic SIP (sterilization-in-place)
The steam sterilisation process is applied to all equipment including the blender.
Do NOT operate the equipment during the steam sterilisation process.
The parts and the materials will not su󰀨er damage provided the instructions set out in
this manual are followed.
Cold liquid cannot be introduced until the blender temperature is below 60ºC (140ºF).
The blender generates a substantial pressure loss through the sterilisation process. We
recommend the use of a bypass circuit provided with a discharge valve to ensure that the
steam or overheated water sterilises the entire circuit.
Maximum conditions during the steam or overheated water SIP process:
a. maximum temperature: 140ºC / 284ºF
b. maximum time: 30 min
c. cooling: sterile air or inter gas
d. materials: EPDM (the materials HNBR y FPM are not recommended)
