4. General Information
4.1. DESCRIPTION
4.2. OPERATING PRINCIPLE
Mixblend blenders are used to add solids that tend to clump when mixed with liquids. Unlike many
other blender models, the advantage of this blender is that it is suitable for use with products with
higher concentrations of gums and thickening agents. Its eld of application is limited to adding small
amounts of solids that are dispersed and sheared quickly into the product.
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.
ATTENTION
The range of application for each type of blender is limited. The blender was selected for
a given set of conditions when the order was placed. Misuse or its use beyond the ope-
rating limits may be dangerous or cause permanent damage to the equipment. INOXPA
shall not be liable for any damage resulting from the incompleteness of the information
provided by the purchaser (nature of the uid, rpm, etc.)
The Mixblend horizontal blender is a compact unit. It consists of an in-line mixer with a venturi
system in the suction and a hopper with a buttery valve above the venturi system to add solids to
the liquid which it passes for the mixer.
The mixer in-line is in the ME-4100 range. Is a compact design mixer, with axial suction, radial
discharge and sanitary connections.
The ventury system creates negative pressure at the base of the hopper. When the hopper valve
opens, the solid are drawn and easily dissolved as they pass through the mixer housing.
It is recommended to recirculate the product until all the solid/powder product is suctioned in and
then, when the solid product is completely incorporated into the liquid product, continue recirculating
the product for a while to ensure the most homogenous dissolution possible.

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 8.10. Disassembly and assembly of the ME-4105 / ME-4110 in-line mixer.
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)
