Product Overview

Model HTK-NC-01 outdoor milk storage silo from 15,000 L to 120,000 L, built in SUS304 or SUS316L as a three layer tank with insulation and cooling jacket. The inner shell is 3 to 4 mm, the outer cladding 2 mm and the cooling jacket 1.5 mm. It stores fresh milk outdoors at large dairy plants and can also hold other liquid food products. Standard fittings include a side agitator, PT100 thermometer, air ventilation cap, aseptic sample valve, CIP cleaning ball and level instrumentation.

Key Benefits

Outdoor installation frees indoor floor area for processing
Three layer construction with insulation and cooling jacket holds milk temperature
Published shell thicknesses: inner 3 to 4 mm, cladding 2 mm, jacket 1.5 mm
Volumes from 15,000 L to 120,000 L
Side agitator, aseptic sample valve and CIP ball fitted as standard

Problems It Solves

Indoor floor area consumed by storage rather than processing
Milk warming during storage and allowing bacterial growth
Sampling that risks contaminating the stored batch
Vessels that cannot be cleaned in place at this size

Where It Is Used

Applications And Buyers

Application Scenarios

Bulk storage of fresh milk at a large dairy plant
Intake buffer between milk collection and processing
Storing other liquid food products in bulk
Adding storage volume where there is no indoor space

Who It Is For

Large dairy plants
Milk collection and processing centres
Liquid food producers needing bulk outdoor storage
Plants expanding intake capacity

Compared With The Alternatives

Indoor stainless steel storage tank	The silo is insulated and clad for outdoor exposure and reaches far larger volumes; the indoor tank suits smaller volumes and sheltered installation.
Milk cooling tank	The cooling tank actively chills incoming milk; the silo holds already cooled milk at temperature in bulk.

Use Guide

Size the silo from the intake volume and how long milk is held before processing
Obtain foundation loading data before civil design starts
Use the aseptic sample valve rather than opening the manway for sampling
Run CIP as soon as the silo is emptied
