Cooling-Based Dehumidification
Air is circulated across a cold coil and cooled to saturation
Further cooling condenses moisture from the air stream
Dew point reduction is limited by minimum practical coil temperatures
Air is delivered at saturated conditions

Standard Desiccant Dehumidification
The dehumidifier is based on Munters unique Honeycombe® sorption drying wheel:
Process air passes through the drying wheel and leaves the dehumidifier as dry air
Heated reactivation air collects the moisture absorbed by the drying wheel and leaves the dehumidifier as wet air
Air supplied to area has dewpoint below freezing
Supply air acts as a sponge

Food Safety & Inspection Service (FSIS) Regulations
9 CFR § 416.2(d) Ventilation states, “Ventilation adequate to control odors, vapors, and condensation to the extent necessary to prevent adulteration of product and the creation of insanitary conditions must be provided.”
Regulations: Observations and Impacts
This regulation does not provide a solution or a recommendation, just the need to solve the problem. Burden is placed on the processor to decide how to proceed
In fact….the regulation states, “Ventilation adequate to….” which may cause a greater problem if applied literally and without discipline
Adding ventilation may actually increase “sweating” as large amounts of unconditioned outside air can condense on cold surfaces

March 7, 2011

9. 2011 Munters Sales Meeting | Dehumidification for Food Applications
Typical Ventilation Layout
Historically the plant philosophy has been to ventilate to an excess. Exhaust fans in the Pick/Scald area pull air through the plant, increasing infiltration of raw outside air. This is one of the root causes of the problem… and a focal point for its resolution.

Munters Solution
System Sizing:
Obtain Facility TAB Report conducted w/in the past few months and floor plan w/ ceiling heights
Set the “Target Dew Point” slightly below the coldest surface temp (typically 0 -10°F dp)
Calculate and justify the required OA amounts by comparing the larger of:
Process Exhaust + Space Pressurization
And
Required Exhaust for CO2 and Cl2 control
Decouple any extreme exhaust areas w/ individual systems
All OA that enters the facility should be conditioned through air handling system
Estimate total unit CFM based upon the specific area w/ considerations for construction type as well as incorporating the other facilities systems and needs
Review and Implement other parameters as:
Filtration (30% and 55% min)
Reactivation Energy (constant load)
Unit Construction (wash down – NTM)
Pre & Post Cooling (OA Levels)
Controls (Humidity Levels)

Notes
Be careful when discussing drying, make sure they know there is no product drying (yield is very important)
Don’t bid what you know is wrong, let’s talk first
Must sell the end user
Don’t push desiccant where it does not make sense! Be credible.
Talk the talk, understand the application or you will loose credibility
Very competitive Market (pricing), they make less than 1 cent per pound profit
Once a rental goes in, it will not come out until permanent equipment is installed
It’s a very open market, having them talk to one of our existing customers, also, some of our customers will open up their plant for new customers to view
Everyone has worked for or with everyone, good news travels fast, bad news travels faster!

The Munters Solution
Eliminates infiltration load:
Example: If you have a -25 spiral freezer and plant ambient conditions of 75 F DB at 60% RH. Freezer inlets are 2’ x 4’ (assume 150 FPM infiltration)
Using gr/hr / 7000 = (CFM) * (4.5) * (delta gr/lb)
gr/hr / 7000 = (2,400 CFM) * (4.5) * (78.1 – 1.3)
Lb / hr = 118.5
Positive Pressure in the freezer aids in product load

26. 2011 Munters Sales Meeting | Dehumidification for Food Applications
Notes
We are handling the infiltration load. Product load is a lot more difficult to control, once the moisture enters the freezer, it’s there.
Don’t promise “no defrost cycles”. They can’t run 24/7, 365 days without a defrost cycle (or shut down).
Find out what the customer currently experienced, what they are looking for (do they get better performance in the winter time)
Try to determine the infiltration load and product load
