Company Overview
Hemp Acres is a small processing facility that makes a variety of consumable products from locally
grown industrial hemp seeds and flower. The manufacturing process begins by cleaning the grain of any
foreign seeds and debris to a level of 99.9% pure hemp seed. Once clean, the grain is then fed i nto a
screw press, where the oil is extruded from the hemp seed. The grain being fed through the press
exceeds 140℉, ensuring a kill step. After passing through the press, the oil separates from the seed,
collected and passes through a filtration process. The hemp meal (cake) is milled and sifted to collect the
protein powder.
• Seed Cleaning (described in this plan)
• Hemp Seed Oil (described in this plan)
• Hemp Protein Powder (described in this plan)
The hemp seed oil and protein powder are made 5 days a week in one 5-hour production shift, followed
by 3 hours of sanitation. Dry cleaning is used in production area, with select pieces of equipment being
cleaned in a three-compartment sink, or sanitized and washed down in place. Water is treated and
tested per EPA requirements by the county. An integrated pest control program is also in place.

Process Narrative
Ingredients and Packaging Material
Processing material is purchased from local farmers and delivered on site by farmer. Supplier that
provide hemp grain have had their grain load sampled for microbial content by Minnesota Valley Testing
Labs. Each delivery is administered a lot number to ensure traceability to the source of grain. Packaging
material are purchased from an approved supplier that complies with internationally recognized food
safety and quality systems.
Receive Hemp Grain
Hemp Grain – Received by the semi-load.
Unloading of the hemp grain is transferred from the semi-truck via Hemp Acres grain vacuum, and
blown into 4000bu. Hopper bin. A lot number is assigned with each delivery and a copy is given to both
Hemp Acres and the deliverer.
Receive Packaging
Bags and bottles are delivered in bulk to the facility. Suppliers provide a certificate of conformance that
packaging materials and inks meet food safety and regulatory requirements.
Store Hemp Grain
Ingredients are comprised only of raw hemp seed. Once processed the ingredients are stored in the
facility (temperature kept below 70℉). All containers are sealed to avoid cross-contact and cross-
contamination during storage.
Store Packaging
Buckets, bottles, and sacs are stored in a dry dedicated space within the facility. Packaging is used First-
In-First-Out.
Clean Hemp Grain
Grain is augured form 4000 bu. Hopper bin to air screener. The grain falls onto two screens with specific
slotted holes to size the grain and remove foreign seeds. Air is applied to both the top screen and
bottom screen to blow off debris. The grain falls out the clean shoot and into a 13’ elevator leg. The
elevator lifts the grain, unloading into the gravity table. The gravity table uses more air and screening to
remove any seeds that aren’t hemp and remove immature/undesirable seeds. The clean shoot from the
gravity table is now 99.9% pure hemp seed (an acceptable level to process) and is dispensed into a 22’
elevator leg. This leg unloads the cleaned grain into a 3.5-ton bulk hopper tank, which holds clean grain
ready to be processed.
Auger Clean Grain from Outdoor Hopper to Indoor Hopper
Grain is augured from outside hopper to indoor hopper. The indoor hopper gravity feeds the presses,
removing the oil from the seed.

KK40 Screw Pressing
Heat sleeves are applied to the screw press to raise the temperature of the barrels to 200℉. This warms
the barrels allowing for the seed to begin crushing. The press is adjusted accordingly to allow for the
maximum amount of oil to be squeezed from the seed. The press heads stay a constant temperature
above 140℉ and under intense pressure, ensuring a kill step at this point. Once the press is set, it runs
untouched until 300L oil tank is full.
Hemp Seed Oil
There are two troughs that separate the oil from the cake. The oil collects and flows from the trough
into a 300L stainless steel tank. A substantial amount of sediment from the press falls into the tank as
well, which is a crucial part of the filtering process.
Filtering/Pump
Once the desired amount of oil is collected in the dirty oil tank, the press is shut down so filtering can
commence. A ratio mixture of Diatomaceous Earth (DE) is added to the oil and a stirrer is turned on to
agitate the sediment and DE together. Once a desired mixture is achieved, the oil is pumped through a
screening plate filter under pressure. This process circulates the oil through the filter, back into the dirty
oil tank. After about 1 hour of running, the DE and sediment have filtered the oil ≤ 1 micron, and the oil
is pumped into the 2nd mixing tank. Now the sediment is removed from the filter frames and cleaned.
The oil will go through one more step to remove the chlorophyll and any heavy metals which will ensure
stability of the oil.
With the stirrer activated, Bleaching Clays (BE) and DE are added back into the dirty oil tank. Once the
desired mixture is set, the pump is turned on, moving the oil back through the filter for about 1 hour (or
until desired levels of purity are met). Once the oil meets our set standards, a bypass valve is opened,
passing through a 1-micron filter, filling a 300L stainless steel tank, or 55-gallon drum, with clean oil.
Filling (5-gallon pails, 55-gallon drum)
The identity of the 5-gallon pail or 55-gallon drum is confirmed for each batch placed on the line to
ensure that it is the correct material and proper SKU #. 5-gallon buckets are filled directly by hand from
the 300L clean oil tank. 55-gallon drums are filled directly from a filling hose off the 1-micron filter. Once
filled they are moved down the line to be capped, sealed, and labeled for completion.
Store, Ship
Jugs, pails, and drums are stored in a designated area in the facility or shipped out immediately upon
customers’ requests.
Hemp Seed Cake
The cake is extruded hot off the press and falls into a designated “cake trough”. In this trough is a slow-
moving stainless-steel auger which conveys the cake into a designated “cake hopper”, cooling it along
the way. Once to the end of the trough, the cake falls into the hopper and awaits milling.

SUPERSEDES
Milling
Connected to the cake hopper is a stainless-steel flighting auger. Once this flighting auger is initiated,
the caked travels up to 13’, unloading into a grinder. This grinder spins at high rpm’s, pulverizing the
cake into a fine powder and passes through a screen.
Sifting
In one fluid motion, the pulverized cake falls from the grinder, through food grade tubing, and onto a
sifting screener. The sifter is aggressively vibrating, allowing for finer particles (protein) to fall through,
while leaving the larger particles (fiber) on top of the screen. The two particles exit the screen through
spouts and fall through more food grade tubing. Critical control point to ensure no metal can pass
through a .35mm screen.
Metal Detection
As the protein exits the sifter, it falls through a food grade tube which passes through a calibrated metal
detector. This ensures no metal is ending up in the sifted protein.
55-Gallon Drum
As the protein falls through the metal detector, we fill 55-gallon drums at a time to ensure no metal
shavings are in the final protein sacs.
Filling (20lb sacs)
When the 55-gallon drum is close to being full, it is transferred out with a new drum. We then scoop
from the 55-gallon bucket into 20lb food grade bags for wholesale. Sacs are sealed, dated, labeled, and
ready for shipment.
Store, Ship
Sacs are stored in a designated area within the facility or shipped out immediately upon customers’
requests.

Hemp grain is hypoallergenic; therefore, no risk is currently present in the processing of hemp grain.
Allergen Cleaning Implications: (Required)
Allergen cleaning is unnecessary due to the fact we only deal with the hemp grain which is
hypoallergenic.
Sanitation Preventive Controls
Zoning and Related GMP Controls
The processing areas are maintained at a higher hygiene level than receiving, storage, and shipping area,
as specified in SOP 15-123 – High Hygiene Sanitation Procedures.
As specified in SOP 15-456 – Employee Hygiene in High Hygiene Areas, employees must put on smocks
that do not have pockets, change into factory shows, put on protective equipment (hair net, beard net),
and wash their hands before entering processing and production area.
Filling area is maintained at the same hygiene level as the processing area (See SOP 15-789 – Filling
Procedures).
Equipment and utensils that are cleaned out-of-place are cleaned and sanitized in a wash area adjacent
to the processing area. Clean equipment is dried and stored on tables and racks in an area adjacent to
the processing area. Cleaning a sanitation equipment has a dedicated location to store sanitation and
cleaning equipment.
Cleaning and Sanitation
The facility, including loading areas are dry cleaned. Processing area, and storage area are maintained
dry during production. Lines and equipment are wet cleaned and sanitized before each new batch of
